Sagittarius A*, abbreviated as Sgr A* (/ ˈ s æ dʒ ˈ eɪ s t ɑːr / SADGE-AY-star [3]), is the supermassive black hole [4] [5] [6] at the Galactic Center of the Milky Way.Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, [7] visually close to the Butterfly Cluster (M6) and Lambda Scorpii.
The Sagittarius A* cluster is the cluster of stars in close orbit around Sagittarius A*, the supermassive black hole at the center of the Milky Way (in the Galactic Center). The individual stars are often listed as " S-stars ", but their names and IDs are not formalized, and stars can have different numbers in different catalogues .
Sagittarius A (Sgr A) is a complex radio source at the center of the Milky Way, which contains a supermassive black hole. It is located between Scorpius and Sagittarius , and is hidden from view at optical wavelengths by large clouds of cosmic dust in the spiral arms of the Milky Way.
S2, also known as S0–2, is a star in the star cluster close to the supermassive black hole Sagittarius A* (Sgr A*), orbiting it with a period of 16.0518 years, a semi-major axis of about 970 au, and a pericenter distance of 17 light hours (18 Tm or 120 au) – an orbit with a period only about 30% longer than that of Jupiter around the Sun, but coming no closer than about four times the ...
Nu 1 Sagittarii (ν 1 Sagittarii, abbreviated Nu 1 Sgr, ν 1 Sgr) is a triple star system [7] about 1,100 light-years from Earth. Its three components are designated Nu 1 Sagittarii A (officially named Ainalrami / ɛ n əl ˈ r eɪ m i / , the traditional name for the system), [ 8 ] B and C. [ 9 ] A and B themselves form a spectroscopic binary ...
GD-1 is a moving group of old, metal-poor stars located at 8.5 kpc above the galactic disk and spanning 63 degrees across the sky, first identified in 2006 [1].The stream was formed after a globular cluster was disrupted by tidal forces, possibly from the gravitational field of the Milky Way.
Sagittarius’ sun sign is Sagittarius, but you knew that already. As a fire sign, Sagittarius is all about energy, action and motivation . They are often quick to get inspired and make for highly ...
Pi Sagittarii (π Sagittarii, abbreviated Pi Sgr, π Sgr) is a triple star system in the zodiac constellation of Sagittarius. It has an apparent visual magnitude of +2.89, [2] bright enough to be readily seen with the naked eye. Based upon parallax measurements, it is roughly 510 light-years (160 parsecs) from the Sun. [1]
