It is one of the stars that form the Teapot asterism; it marks the junction of the handle and the lid of the Teapot. It has a diameter of about 20 kilometres and its rotation speed at the surface is 30,000 km/h. Sagittarius Zodiac Sign - Character traits - Greek Mythology 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. This is unusually young for such a cluster. LBV 1806-20, a candidate luminous blue variable (LBV) is one of the most luminous stars in our galaxy. It is the most highly magnetized object ever discovered. The system is also known by its traditional name, Arkab, from the Arabic carqb, which means hamstring.. Delta Sagittarii is a multiple star system approximately 306 light years distant in the constellation Sagittarius. Realising Ixion's intentions, Zeus sent a cloud, disguised as Hera, to trick him. The planets SWEEPS-04, orbiting the magnitude 18 star SWEEPS J175853.92291120.6 (F5V), and SWEEPS-11, with the parent star SWEEPS J175902.67291153.5, are among the most distant exoplanets known, both located at a distance of 27,710 light years from Earth. The nebulas central star is more than 12,000 times more luminous than the Sun. 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. The archer is usually identified as the centaur Chiron, though sometimes held to be a similar figure known as Crotus, a satyr. The constellation Sagittarius contains 17 named stars. Sagittarius sits in the 240-270th degree in the zodiac among Scorpio and Capricorn. The nebula lies at a distance of 7,800 light years from Earth and has a 16th magnitude central star. Chiron was an intelligent, wise, and good-natured creatureunlike most of his kind. Because it has an imposing size and energy, Sagittarius A East is believed to be a remnant of a star that came close to the central black hole and was gravitationally compressed. The Gamma designation used to be shared by two star systems in Sagittarius, Gamma-1 and Gamma-2, which were separated by 0.86 in the sky. Ross 154 was originally catalogued by the American astronomer and physicist Frank Elmore Ross in 1925. In mythology, Centaurs were hard drinkers, unreliable, misleading, crude, wild, and adulterous. Image: ESO. The cluster was discovered by William Herschel on May 24, 1784. Sagittarius is a masculine sign and ruled by Jupiter, and is balanced and complemented by the opposite sign of Gemini, ruled by Mercury. The star was last occulted by a planet on November 17, 1981, when Venus passed in front of it. They have the head and torso of a man, but the bottom half of a hoofed beast. Satyrs have human heads and torsos with goat legs (and sometimes horns). The cluster has an apparent magnitude of 9.5. Westerhout 31 (W31) is a massive H II region in Sagittarius. It is also notable for being one of only four known globular clusters that contain a planetary nebula. The origin of Eta Sagittariis proper name Sephdar is unknown. It has a similar structure to the Small Magellanic Cloud, the dwarf galaxy in the constellation Tucana. 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. Sagittarius is an astrological sign transitted by the Sun from approximately November 23rd to December 22nd. Another companion star is only 13th magnitude and can be seen 33 arc seconds away from the primary, while the faintest star in the system is 10th magnitude and is separated from the brightest star by 93 arc seconds. Phi Sagittarii is a B8 class giant approximately 231 light years from Earth. The neighboring constellations are Aquila, Capricornus, Corona Australis, Indus, Microscopium, Ophiuchus, Scutum, Scorpius, Serpens Cauda and Telescopium. They also look a lot alike. The sign is represented by the toxophilite or a centaur, which is half human and half pony. The two-lobed nebula surrounds the central hot white dwarf that produces a hot wind with a speed of 300 km/s. In Greek mythology, Sagittarius is Chiron, a centaur who was a teacher to gods and heroes, like Achilles. Messier 70 offers a special case because it has undergone what is known as a core collapse. (In 2003, the Canis Major Dwarf Galaxy was discovered and recognized as the nearest neighbour.). NGC 6520 is an open star cluster with an apparent magnitude of 9.0. Spanning an area of 150 light years across, Sagittarius B is one of the largest molecular clouds in our galaxy and the single largest one in the vicinity of the galaxys core. The cluster has a diameter of about 6 arc minutes. Terzan 7 is the brightest of the six globulars discovered by Agop Terzan in 1968. Sagittarius is most often associated with Crotus, the son of Pan (the goat-god) and Eupheme (the Muses' nurse). Ferraro. The brightest one has a magnitude of 9.2. About a fifth of the more than 150 globular clusters in the Milky Way have undergone a core collapse. Its estimated age is between 3 and 4.5 million years. 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. Together these are providing a vast legacy of publicly available data for the global astronomical community. It has an apparent magnitude of 3.97 and is approximately 170 light years distant. NGC 6440 is another globular cluster in Sagittarius. Sagittarius There are two separate myths connected to the Archer, but both share themes of knowledge, art, and wisdom. It has an apparent magnitude that varies from 6.5 to 14.0 over a pulsational period of 732 days. It is one of only four star systems known to be hydrogen-deficient, which makes it difficult to classify U Sgr. It is good to remember the reason why Sagittarius is a centaur in the first place. It was originally discovered by Charles Messier in 1764. Located on the far side of our galaxy, the cluster is heavily obscured by dust, but visible in infrared wavelengths.
