M32 is a dwarf elliptical galaxy of only about 3 billion solar masses, and a linear diameter of some 8,000 light years, which is very small compared to its giant spiral-shaped neighbor the Andromeda galaxy. It is a member of the Local Group. The M32 is located 2.65 million light years away in the constellation Andromeda.

Tidal effects trigger a massive star burst in the core of the M32, which explains its high density. The M32 has an outer disk.
