How are galaxy found?
Almost all stars are located in galaxies. When galaxies interact with each other, a very small number of stars may get lost and end up outside of a galaxy.

Its central massive object is a supermassive black hole of about 4 million solar masses, which powers the compact radio source Sagittarius A*, which is almost exactly at the galactic rotational center.
