Galaxy morphological classification is a system used by astronomers to divide galaxies into groups based on their visual appearance.Hubble sequence is a morphological classification scheme for galaxies invented by Edwin Hubble in 1936.he divided the galaxies into 1) elliptical galaxies2)Spiral galaxies3)Lenticular galaxiesSource:wikipedia
Galaxies ARE groups of stars. Lots of stars though. Not just like 2 or 3...
are spiral galaxies are generally older than elliptical
The estimated number of galaxy groups, given that there are 100 billion galaxies in the universe, is 100 to 200 billion.

Yes, mammals are divided into many sub-groups.
Galaxies that travel together through space are called galaxy groups or galaxy clusters. These are systems of galaxies bound together by gravity.
Most galaxies, even our own, are found in groups or clusters. For example, the Local Group contains several galaxies including the Milky Way, Andromeda, and the Magellanic clouds.
We are part of the Local Group. The Local Group contains the Milky Way, two other major galaxies, and dozens of dwarf galaxies. The Local Groups is a group of galaxies which, as galaxies go, are close to us.
Stars, planets, moons, comets, asteroids and other phenomena.
