Messier included the cluster in his catalogue in June 1764. Normally, the white dwarf stage is the last in the life cycle of a low-mass star. Although centaurs could be male and female, the male ones came to be associated with lust: these part-human creatures seemed to be jealous of the fully human women they encountered and wanted to carry them off at almost every opportunity. It has an estimated age of 13.06 billion years. History and Mythology Of The Sagittarius Constellation. NGC 6822 has an apparent magnitude of 9.3 and is approximately 1.63 million light years distant. The object is actually a small white dwarf star undergoing a helium flash one of only a handful of examples of such an event ever witnessed by astronomers. Sagittarius is usually depicted as a centaur holding a bow and arrow. It is one of the constellations of the zodiac. Hercules accidentally shot Chiron with a poisoned arrow while hunting, and since he. In Sagittarius Mythology, Sagittarius is described as The Centaur (one-half horse, one-half human). It has an apparent magnitude of 13 and lies at an estimated distance between 3,000 and 8,000 light years from Earth. The spiral structure Sagittarius A West appears like a three-arm spiral and is sometimes called the Minispiral. The image of the Peony Nebula star was taken by NASAs Spitzer Space Telescope in its naturally dusty region. It has a faint 14th magnitude companion 32 arc seconds away. SGR 1806-20 was identified as a soft gamma repeater in 1979. The most notable of these regions, the radio-emitting nebula G10.3-0.3, is home to the cluster 1806-20, which contains an O-type supergiant, two blue hypergiants, three Wolf-Rayet stars, the luminous blue variable LBV 1806-20 and the magnetar SGR 1806-20. The stars spectral type is estimated to be between O9 and B2 and may be variable. M 1-42 is another planetary nebula in the constellation, located at a distance of 10,000 light years from Earth. Nir al Beldat was later translated into Latin as Lucida Oppidi, which means the brightest of the town.. One could easily interpret the shape as that of a half-man/half-horse instead of a half-man/half-goat. Some stars maintain relatively circular orbits, while others loop out into the clusters fringes. It is elliptical in shape and about 32 arc minutes across in size. At the equator, the pulsar is spinning at a speed of more than 70,000 km/s, or about 24% of the speed of light. Globular clusters are dense collections of old stars. NGC 6553 is loosely concentrated and has an apparent diameter of 8.2 arc minutes. Before that, Mercury occulted the star on December 5, 1865. It represents the archer. It is a satellite galaxy of the Milky Way and headed for a collision with our galaxy. Nunki has a faint (magnitude 9.5) companion about 5.2 arc minutes away. Peering through the thick dust clouds of our galaxys central parts (the bulge) with an amazing amount of detail, a team of astronomers has revealed an unusual mix of stars in the stellar grouping known as Terzan 5. Named after the nebula that surrounds it the Peony Nebula the Peony Star is a Wolf-Rayet star with an absolute magnitude of -11.5. Other similar ripples of heated matter thrown out by feisty young stars are dotted across Barnards Galaxy. The galaxy was named after the American astronomer E.E. Messier 23 is an open star cluster, discovered by Charles Messier in June 1764. The shared birthday is another uncommon property; a large number of globular clusters, both in the Milky Way and in other galaxies, seem to have at least two clearly differentiated generations of stars that were born at different times. Successive generations of stars have built up the metallic abundances we see today. Messier 70 is a globular cluster in Sagittarius, located close to the Galactic centre. In English, the constellation is known as the Archer. The clusters age and low levels of nickel found in it led astronomers to believe that it may have originated in the Sagittarius Dwarf Spheroidal Galaxy (Sag DEG). KW Sagittarii is one of the largest known stars. It has an apparent size of 4.75 by 4.75. The sign, which is represented by the archer's arrow, is ruled by Jupiter. As understood through the centaur, the Sagittarius sign is as optimistic as the archer but . Image: ESA/Hubble & NASA, acknowledgement: M. Novak. Alpha Sagittarii is a blue dwarf belonging to the spectral class B8V. These same colours can be seen in the famous and impressive Ring Nebula (heic1310), a prominent example of a nebula like this one. The Terebellum is a quadrilateral formed by four fourth magnitude stars in Sagittarius, all within two degrees of each other: Omega Sagittarii, 59 Sagittarii, 60 Sagittarii and 62 Sagittarii. The companion star has an apparent magnitude of 5.84 and is located about 359 light years from Earth. It was discovered by Charles Messier on August 31, 1780, along with another globular cluster, Messier 70. It lies at a distance of 35,500 light years. This dazzling image shows the globular cluster Messier 69, or M69 for short, as viewed through the NASA/ESA Hubble Space Telescope. Most likely, the primary component is an A type supergiant. It is approximately 77.3 light years distant. Sag DEGs ellipse is already extended around our galaxy, and the main cluster will pass through the galactic disc of the Milky Way in the next million years. (Flare stars are typically dim red dwarfs or less massive brown dwarfs.). NGC 6578 is a planetary nebula occupying an area of 8 arc seconds. Another aspect of M69 lends itself to the bejewelled metaphor: As globular clusters go, M69 is one of the most metal-rich on record. Centaurs have four legs, and are half-man, half-horse; satyrs have two legs and are half-man, half-goat. Sigma and Tau Sagittarii mark the handle, Delta, Epsilon, Zeta and Phi Sagittarii form the body of the Teapot, Lambda Sagittarii marks the point of the lid and Gamma-2 Sagittarii marks the tip of the spout. The cluster is about 19 light years across. Both creatures were very similar to one another and the general meaning of the Sagittarius myth remains the same, regardless of whether you think its representative had two legs or four. It's not a mindless ramble for these folks, either. It is one of the nearest globular star clusters to Earth. Delta Sagittarii is a multiple star system approximately 306 light years distant in the constellation Sagittarius. In honor of Chiron's sacrifice, Zeus created the constellation Sagittarius in his likeness. However, because of its compact nature, M75 can barely be distinguished from a star when viewed in binoculars. One day, when Heracles was hunting, he accidentally shot Chiron in the knee with a poison arrow. It is one of the stars that mark the handle of the Teapot asterism. It is not fully understood how planetary nebulae form such a wide variety of shapes and structures; some appear to be spherical, some elliptical, others shoot material in waves from their polar regions, some look like hourglasses or figures of eight, and others resemble large, messy stellar explosions to name but a few. Mythology of the constellation Sagittarius. Messier 25 is an open cluster with an apparent magnitude of 4.6, about 2,000 light years from Earth. The brightest stars in the cluster are 16th magnitude. The cluster lies only 10,400 light years from the Galactic centre. Sagittarius in mythology. Sagittarius is one of the 88 modern constellations, . This may indicate that, like the better known Messier 54 and Omega Centauri, Terzan 5 is not a true globular cluster, but possibly the remaining core of a dwarf galaxy disrupted by the Milky Way in the distant past. It has about a third of the luminosity of the Eta Carinae binary system in the constellation Carina and is believed to radiate as much energy in 20 seconds as the Sun does in a year. In Greek mythology, Sagittarius represents a centaur, a half human, half horse creature with the torso of a man and the body and four legs of a horse. Yet, it isn't the correct one, according to Gods and Monsters, which holds that the constellation Zeus created in Chiron's honor was actually Centaurus, a constellation that borders Libra (via Sea and Sky). Being half human aligned the centaur with intellect and civility, while the horse end symbolized. Delta Sagittarii has a radius 62 times solar, a mass about five times solar, and is 1180 times more luminous than the Sun. Pabilsag is an unusual centaur-like creature who fires arrows. The planetary nebula in the Sagittarius Cluster, designated GJJC1 is believed to be only 6,000 years old and has a blue star at the centre. Observations in 2009 revealed that the cluster contains at least two generations of stars, one with an estimated age of 12 billion years and another about 4.5 billion years old. Because the stars in globular clusters are ancient, their metallic abundances are much lower than more recently formed stars, such as the Sun. Chiron was a kind, talented, and gentle creature. Satyrs have two legs while centaurs have four. The cluster was discovered by Charles Messier in 1778. Most sources identify Sagittarius as Chiron, the son of the Titan Cronus, according to Globe at Night. The cluster has an apparent magnitude of 11.29 and lies at a distance of 24,100 light years from Earth. It contains very few variable stars. Its old astronomical symbol is (). Alternatively, some mythology identifies Sagittarius as the son of Pan, the god who created archery. Messier 28, based on observations made with the NASA/ESA Hubble Space Telescope, and obtained from the Hubble Legacy Archive, which is a collaboration between the Space Telescope Science Institute (STScI/NASA), the Space Telescope European Coordinating Facility (ST-ECF/ESA) and the Canadian Astronomy Data Centre (CADC/NRC/CSA). The Teapot in Sagittarius, image: Wikisky. The brightest star in Sagittarius is Kaus Australis, Epsilon Sagittarii (spectral class B9.5 III), with an apparent magnitude of 1.79. This galaxy is currently colliding with, and being absorbed by, the Milky Way, which is a monster in size when compared to this tiny one. NGC 6589 is a reflection nebula that occupies an area of 5.0 by 3.0 in apparent size. The last time this happened was on November 19, 1984, when Venus passed in front of the star, eclipsing it. Terzan 5 contains at least 34 and up to 200 milisecond radio pulsars (pulsars with a rotational period of 1-10 miliseconds), including PSR J1748-2446ad, the fastest spinning pulsar known, which rotates 716 times a second with a rotation period of 1.40 miliseconds. It can be found between the Sagittarius Star Cloud (Messier 24) and the Omega Nebula (Messier 17). The cluster has an apparent diameter of 7 arc minutes and a visual magnitude of 9.47. The brightest stars in the cluster are 7th magnitude. The apparent magnitude of Polis A ranges from 3.84 to 3.96. The most prominent members are Wolf-Rayet stars and O-type supergiants. First detected in 1999, V4641 Sgr is a variable X-ray binary system once considered to be the closest black hole to Earth, at a distance of about 1,600 light years. It was discovered by the French astronomer Pierre Mchain in 1780. Its estimated age is between 3 and 4.5 million years. Sigma Sagittarii is sometimes also known as Nunki. Never observed anywhere in the bulge before, this peculiar cocktail of stars suggests that Terzan 5 is in fact one of the bulges primordial building blocks, most likely the relic of a dwarf galaxy that merged with the Milky Way during its very early days. The binary system has a combined apparent magnitude of 2.60. The star is probably a B or O type main sequence dwarf that has accreted much of the primary stars mass. This image from the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESOs La Silla Observatory in Chile, shows the bright star cluster NGC 6520 and its neighbour, the strangely shaped dark cloud Barnard 86. The star cluster 1806-20 is home to many massive stars that are expected to end their lives as supernovas in the next few million years. It is between 18,000 and 19,000 light years distant and has an apparent magnitude of 7.66. It was originally discovered by Charles Messier in 1764. VX Sagittarii lies at an approximate distance of 5,150 light years from Earth. Most stories come to the conclusion that the myth of the constellation Sagittarius is the tale of the centaur Chiron. 62 Sagittarii (or c Sagittarii) is an M-type giant at the southwest corner, about 450 light years from Earth. Emerson/VISTA. Individuals born between November 22 and December 21 are known to be Sagittarius individuals. A gas giant planet was discovered orbiting the orange dwarf HD 164604 (K3.5Vk) in 2010. It has a mass of about 36 solar masses, which now puts it behind more than a dozen massive stars, including four members of the Arches Cluster. All Rights Reserved. This vast ball of ancient stars is located at a distance of about 17,000 light-years from Earth. The constellation name Sagittarius is pronounced /sdtris/. With a mass of 10,000 solar masses, it is about 10 times more massive than typical open clusters in the Milky Way. This is unusually young for such a cluster. It is now believed to be located at least 15 times farther away. The myth behind Sagittarius actually refers to Crotus, a satyr that lived on Mount Helicon with the Muses. M54 is believed to belong to the Sagittarius Dwarf Elliptical Galaxy. It is located approximately 17,300 light years from Earth. It is a fire sign, considered to be a masculine, positive, and extrovert in character. The cause of these outbursts is not understood, but the rapidity with which they rise and fall indicates that they are occurring near the event horizon, or point of no return, around the black hole. Some of the brightest stars in Sagittarius Delta, Epsilon, Gamma-2, Lambda, Zeta, Phi, Tau and Sigma Sagittarii form an asterism known as the Teapot. Beta-2 Sagittarii, or Arkab Posterior (because it trails after Beta-1), is a giant star belonging to the spectral type F2III. Mu Sagittarii is a multiple star system in Sagittarius, with individual components designated Polis A through Polis E. Its traditional name, Polis, comes from the Coptic Egyptian word for foal.. About 25 stars in the cluster are of magnitude 9 to 12. The cluster has an apparent magnitude of 6.9 and is about 2,150 light years distant. NGC 6624 is another globular cluster in Sagittarius. It is the densest concentration of stars that can be seen using binoculars; about a thousand stars are visible within a single field of view. Phi Sagittarii is a B8 class giant approximately 231 light years from Earth. Also prominent in the upper left of this new image is a striking bubble-shaped nebula. The nuclear fusion that powers stars created all of the metallic elements in nature, from the calcium in our bones to the carbon in diamonds. The three-letter abbreviation, adopted by the International Astronomical Union (IAU) in 1922, is Sgr. The gamma ray burst was so powerful that it hit the Earths ionosphere and briefly expanded it. The proper names of stars that have been officially approved by the International Astronomical Union (IAU) are Ainalrami, Albaldah, Alnasl, Arkab Posterior, Arkab Prior, Ascella, Belel, Gumala, Kaus Australis, Kaus Borealis, Kaus Media, Nunki, Pincoya, Polis, Rukbat, Sika, and Terebellum. In Babylonian mythology, Sagittarius is associated with the centaur-like god Nergal, and depicted with two heads one human and one panther and also wings, and the stinger of a scorpion positioned above a horses tail. Like several other stars in Sagittarius, Albaldah is near the ecliptic and can occasionally be occulted by the Moon and planets. The Red Spider Nebula is a planetary nebula that occupies an area of 1.5 arc minutes in the northwestern part of Sagittarius. Another Greek myth connects Sagittarius with Crotus, the son of Pan, the goat-god, and Eupheme, the nurse of the Muses. It is also catalogued as ESO 456-70. The genitive form of Sagittarius, used in star names, is Sagittarii (pronunciation: /sdtria/). It's easy to see why the myths behind Centaurus and Sagittarius often get confused. The brightest stars in the cluster are 16th magnitude. NGC 6822 is a barred irregular galaxy that belongs to the Local Group of galaxies. They both were known to hunt with a bow and arrow (though this is a bit misleading as centaurs did not traditionally use a bow and arrow. The region has relatively low amounts of dust and allows a view of the Galactic centre. Satyrs did.) Ascella also has a dim companion 75 arc seconds away. Located on the far side of our galaxy, the cluster is heavily obscured by dust, but visible in infrared wavelengths. It does not really have the structure of a spiral. During this time the black hole flared up in X-ray intensity half a dozen or more times. Messier 70 offers a special case because it has undergone what is known as a core collapse. It has an apparent magnitude of 5.1 and is approximately 10,600 light years distant. Image: ESO/J. The Trifid Nebula has an apparent magnitude of 6.3 and is approximately 5,200 light years distant. Hurt, who led the team that confirmed the discovery. By 1999, the star became invisible in optical wavelengths as a result of being obscured by a very thick shell of dust. Image: NASA, ESA, STScI, and G. Piotto (Universit degli Studi di Padova), and E. Noyola (Max Planck Institut fr extraterrestrische Physik). Myth of Sagittarius. Mythology. Return from Sagittarius Myth to the Constellation Myths page. The significance of the name is unknown, except that it is a proper name. The red dwarf MOA-2009-BLG-387L, located almost 20,000 light years away, is host to an orbiting planet with a mass between 1.0 and 6.7 times that of Jupiter. Sagittarius is Latin for "archer," and since ancient times the constellation has been represented as a creature wielding a bow and arrow. Peony Star has an estimated mass of about 100 solar masses and a radius 92 times solar. Satyrs have human heads and torsos with goat legs (and sometimes horns). It is made of clouds of dust and gas that circle Sagittarius A* and fall onto it at exceptionally high velocities, up to 1000 kilometres per second. This is the Sagittarius horoscope symbol and the character that represents this zodiac sign. The name is derived from the astronomical constellation Sagittarius, meaning "archer" in Latin. The Sagittarius Dwarf Elliptical Galaxy has an apparent magnitude of 4.5 and is approximately 65,000 light years distant. The archer is usually identified as the centaur Chiron, though sometimes held to be a similar figure known as Crotus, a satyr. It was recovered by archaeologists and made public by Richard Hinckley Allen in his book Star names, their lore and meaning. The third star in the system is an O-type star with an apparent magnitude of 15.36. The star lies approximately 228 light years from Earth. Lambda Sagittarii marks the handle of the Teapot asterism (see below) and points to the famous interstellar cloud, the Lagoon Nebula. M75 is believed to be around 13 billion years old and sits approximately 67,500 light-years away from Earth. M21 has an apparent magnitude of 6.5 and lies at an approximate distance of 4,250 light years from Earth. He even invented the bow, according to Greek mythology. Sagittarius is symbolized by the centaur, half-human and half-horse beings in Greek mythology. But why were they immortalized in the stars? There are no meteor showers associated with the constellation. It has an apparent magnitude of 3.17. Also known as NGC 6822, this dwarf irregular galaxy is one of the Milky Ways galactic neighbours. These are pulsating stars belonging to the spectral class A (and occasionally F), usually with a mass of about half the Suns, used as standard candles to measure galactic distances. In this picture, foreground stars look big and golden when set against the backdrop of the thousands of white, silvery stars that make up M69. Sagittarius in Mythology The story of Sagittarius originates from Greek mythology, specifically that of Chiron, an immortal centaur who acted as teacher to many ancient Greek heroes. It was first discovered by the French astronomer Guillaume Le Gentil in 1747. The Trifid Nebula is about 28 arcminutes across in size. Because he was close to the Muses, they were the ones who asked Zeus to place him in the sky. In Greek mythology, Sagittarius is commonly thought to represent a centaur, a war-like creature with the torso of a man and the body of a horse. Edward Emerson Barnard catalogued it as IC 4690 in August 1905. Beta-1 Sagittarii, or Arkab Prior (prior because it leads Beta-2 across the sky), is a double star approximately 378 light years distant. Before being assigned to Sagittarius, the star system was known as Beta Telescopii. It cannot be seen visually, but must be observed in radio, X-ray and infrared bands. It has a radius 11 times solar and is 52 times more luminous than the Sun. NGC 6723 is a globular star cluster in Sagittarius, near the border with Corona Australis. The myth of centaurs: summary. It goes by many different names: Omega Nebula, Horseshoe Nebula, Lobster Nebula, Swan Nebula, Checkmark Nebula, and Sharpless 45. Beta Sagittarii is a designation shared by two star systems, Beta-1 Sagittarii and Beta-2 Sagittarii, which lie 0.36 apart in the sky. Sagittarius is often misinterpreted just like Virgo is. . The planetary nebula Henize 3-1475, also catalogued as IRAS 17423-1755, lies at an approximate distance of 18,000 light years from Earth. Sagittarius constellation lies in the southern sky. Centaurs were often associated with the abduction (or attempted abduction . The clusters NGC 6522 and NGC 6528. Soft gamma repeaters (SGR) are objects that emit enormous bursts of gamma-rays and X-rays at irregular intervals. It has a half-mass diameter of 102 and linear radius of 2.7 light years. Would you prefer to share this page with others by linking to it? The nebulas central star is more than 12,000 times more luminous than the Sun. Most likely it comes from different cultural interpretations of the constellations. Image: ESA/Hubble & NASA. About a fifth of the more than 150 globular clusters in the Milky Way have undergone a core collapse. The Box Nebula, catalogued as NGC 6445, is a planetary nebula with a visual magnitude of 11.2. Quarters are always tight in globular clusters, where the mutual hold of gravity binds together hundreds of thousands of stars in a small region of space. Sagittarius has seven stars brighter than magnitude 3.00 and three stars located within 10 parsecs (32.6 light years) of Earth. Its traditional name, Ascella, means armpit in Latin. Messier 28 was the first globular star cluster in which a milisecond pulsar (a pulsar with a rotational period between 1 and 10 miliseconds) was discovered in 1986. As the stars interact with each other over time, lighter stars tend to pick up speed and migrate out toward the clusters edges, while the heavier stars slow and congregate in orbits toward the centre. The cluster occupies an area of 2 of apparent sky. The cloud is about 600 light years wide and approximately 10,000 light years distant. On 27 December, 2004, the brightest gamma ray burst ever detected outside the solar system was recorded emanating from the star, with an absolute magnitude of about -29. The cluster has a visual magnitude of 8.06 and lies at a distance of 19,600 light years from Earth. The stars agony has culminated in a wonderful planetary nebula known as NGC 6565, a cloud of gas that was ejected from the star after strong stellar winds pushed the stars outer layers away into space. Image: ESO. The clusters small central region has one of the highest star densities in the Milky Way. The Omega Nebula is an emission nebula in Sagittarius. The field of view is 35 x 34 arcmin. NGC 6624, based on observations made with the NASA/ESA Hubble Space Telescope, and obtained from the Hubble Legacy Archive, which is a collaboration between the Space Telescope Science Institute (STScI/NASA), the Space Telescope European Coordinating Facility (ST-ECF/ESA) and the Canadian Astronomy Data Centre (CADC/NRC/CSA). Together these are providing a vast legacy of publicly available data for the global astronomical community. Evidence shows that Terzan 7 used to belong to a small galaxy called the Sagittarius Dwarf Galaxy, a mini-galaxy discovered in 1994. He later included it in his catalogue. Sagittarius symbolism and mythology. The glyph is the upward-pointing arrow of the archer, ready to be fired into the future. Chiron was wise and skilled not only in the arts of war but also healing and philosophy. It is located only 5.41 light years from Barnards Star in the neighbouring constellation Ophiuchus. Image: ESA/Hubble and NASA. Sagittarius, the centaur, is the ninth sign in the Zodiac and represents those born between Nov. 22 and Dec. 21. Sagittarius contains 15 Messier objects: Messier 8 (M8, NGC 6523, Lagoon Nebula), Messier 17 (M17, NGC 6618 Omega, Swan, Horseshoe or Lobster Nebula), Messier 18 (M18, NGC 6613), Messier 20 (M20, NGC 6514, Trifid Nebula), Messier 21 (M21, NGC 6531), Messier 22 (M22, NGC 6656, Sagittarius Cluster), Messier 23 (M23, NGC 6494), Messier 24 (M24, NGC 6603, Sagittarius Star Cloud), Messier 25 (M25, IC 4725), Messier 28 (M28, NGC 6626), Messier 54 (M54, NGC 6715), Messier 55 (M55, NGC 6809), Messier 69 (M69, NGC 6637), Messier 70 (M70, NGC 6681) and Messier 75 (M75, NGC 6864). Sagittarius is one of the constellations of the zodiac and is located in the Southern celestial hemisphere. Sagittarius, the ninth sign of the zodiac, is the home of the wanderers of the zodiac. The most well-known myth is that of Chiron, the centaur and revered teacher of many Greek heroes. It is obscured from view by large cosmic dust clouds in the galaxys spiral arms. Lambda Sagittarii is what astronomers sometimes refer to as a clump star: one undergoing the final stages of its existence, but stable nevertheless and fusing helium into carbon and oxygen in its core. The origin of Eta Sagittariis proper name Sephdar is unknown. The stars temperature is also variable and changes from about 2,500 K to 3,500 K, which is unprecedented in a star of this type. At the time, Sag DEG was the nearest known neighbouring galaxy of the Milky Way. It was discovered by William Herschel on June 24, 1784. The cluster has an apparent magnitude of 9.5. The cluster has a highly concentrated core, with the majority of M75s stars located in a large nucleus. NGC 6818 is a magnitude 10 planetary nebula in Sagittarius. Image: ESO/VPHAS+ team. The cluster can be seen only 0.8 degrees to the southeast of Delta Sagittarii. Sagittarius is an astrological sign transitted by the Sun from approximately November 23rd to December 22nd. Kaus Australis is the brightest star in the constellation Sagittarius and the 36th brightest star in the sky. 59 Sagittarii (sometimes also known as b Sagittarii) is a K-type bright giant at the southeast corner, about 1,200 light years distant. It is a known X-ray source. The Pistol Star is one of the most luminous stars known. These figures come from Greco-Roman mythology, but it's thought that the ancient Babylonians were the first to identify Sagittarius as an archer, in 11th century B.C. The globular cluster Messier 54 lies at the core of the galaxy. Terzan 5 is a globular cluster about 18,800 light years away in the Milky Way bulge. It was discovered by James Dunlop on June 2, 1826. LBV 1806-20, a candidate luminous blue variable (LBV) is one of the most luminous stars in our galaxy. The stars are 28 arc seconds apart. NGC 6624 contains six confirmed pulsars and a low-mass X-ray binary, designated 4U 1820-30, with an orbital period of only 11.5 minutes. The cluster contains 18 RR Lyrae type variable stars. This, however, only applies to Mars and it happens very rarely. It has an apparent magnitude of 12.87. Messier included it in his catalogue in 1764. The clouds have an ionized surface. The primary component, Arkab Prior A, is a B9 type main sequence dwarf with an apparent magnitude of 3.96, while the companion star, Arkab Prior B, is a class A3 dwarf with an apparent magnitude of 7.4.
