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.
One star, designated S2, was calculated to orbit Sgr A* at speeds of over 5,000 kilometers per second at its closest approach. [13] A gas cloud, G2, passed through the Sagittarius A* region in 2014 and managed to do so without disappearing beyond the event horizon, as theorists predicted would happen. Rather, it disintegrated, suggesting that ...
The largest one is quoted, while the smaller one's mass is not defined. [50] RX J1532.9+3021: 1 × 10 10 [51] QSO B2126-158: 1 × 10 10 [26] – 4.9 +1.13 −1.01 × 10 10 [49] Higher value estimated with quasar Hβ emission line correlation. NGC 1281: 1 × 10 10 [52] Compact elliptical galaxy in the Perseus Cluster. Mass estimates range from ...
The solar mass (M ☉) is a standard unit of mass in astronomy, equal to approximately 2 × 10 30 kg (2 nonillion kilograms in US short scale). It is approximately equal to the mass of the Sun. It is often used to indicate the masses of other stars, as well as stellar clusters, nebulae, galaxies and black holes. More precisely, the mass of the ...
Marking the ninth zodiac sign on the wheel, Sagittarius is a Fire sign that arrives after Scorpio and before Capricorn. It is symbolized by an archer and its season spans Nov. 22 to Dec. 21 in 2025.
The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes. For example, a gigagram ( Gg ) or 10 9 g is 10 3 tonnes, commonly called a kilotonne .
Venus in Sagittarius is a transit that astrologers describe as passionate-inducing. Romance goes hand-in-hand with intellectual stimulation and the ability to leave one's comfort zone.
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 ...
