Supermassive black hole - Wikipedia
Evidence indicates that the Milky Way galaxy has a supermassive black hole at its center, 26,000 light-years from the Solar System, in a region called Sagittarius A* [92] because: The star S2 follows an elliptical orbit with a period of 15.2 years and a pericenter (closest distance) of 17 light-hours ( 1.8 × 10 13 m or 120 AU) from the center ...
