It is an estimated 22 million light years away from the Milky Way and has a diameter of about 60,000 ly. The center of the galaxy is home to an extremely massive black hole of about two billion solar masses, with a total mass between 300 and 400 billion solar masses.
NGC 3115 is sometimes called the spindle galaxy , not to be confused with Messier 102, which is also called.
