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.
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.
A small mass has an extremely small Schwarzschild radius. A black hole of mass similar to that of Mount Everest [ 19 ] [ note 2 ] would have a Schwarzschild radius much smaller than a nanometre . [ note 3 ] Its average density at that size would be so high that no known mechanism could form such extremely compact objects.
Sag A* alone is 4.3 million solar masses. So how can Sag A be only 3.8 million solar masses. I also support that statement, the mass of Sag A* is estimated to be between 4 and 4.7 solar masses so the source of radio emissions must be higher.

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 .
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.
