Elliptical Galaxies

Galaxies that are shaped like fat eggs or footballs. Ellipticals are among the largest galaxies, with some spanning more than one million light-years. They probably formed from the mergers of two or more smaller galaxies, such as spirals. Unlike spirals, where the stars all orbit the center of the galaxy in the same direction, the stars in ellipticals move in random orbits.
