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.
Sgr A East is a supernova remnant (SNR) located 7 light-years from Sgr A* and spanning approximately 27 light-years in diameter, originating from an explosion between 1,000 and 10,000 years ago. [7] Though its status as a SNR was initially debated, [ 7 ] the observed abundance of heavier elements, such as a higher ratio of Mn/Fe and Ni/Fe ...
However, the names of all SI mass units are based on gram, rather than on kilogram; thus 10 3 kg is a megagram (10 6 g), not a *kilokilogram. 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.

If you were born between November 22 and December 21, you may know you’re a Sagittarius. You may even know that you’re such a Sagittarius. But when you dig deep, what even is a Sagittarius?
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 .

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 ...
