dwarf galaxy

(small galaxy with a few billion stars)

The term dwarf galaxy is used for galaxies much smaller than the Milky Way, i.e., of a few billion stars at most, and as small as 100 parsecs across. They can be any of the normal galaxy types, such as a spiral galaxy. Often they are satellite galaxies.

Some more specific terms:

(The term compact galaxy (CG) came into use meaning it has a high surface brightness compared to its apparent diameter, which can be the result of a very high density of stars.)
