Elliptical galaxy - Wikipedia
WEBAn elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image. It is one of the four main classes of galaxy described by Edwin Hubble in his Hubble sequence and 1936 work The Realm of the Nebulae.

WEBAn E0 galaxy looks like a circle. An E7 galaxy is very long and thin. Astronomers have specific mathematical definitions for each number, but these definitions are beyond the scope of this project. With some practice, you can learn to visually tell what type of elliptical galaxy you are observing.

WEBThe distribution of stellar motion determines the final shape of the galaxy (spherical, oblate, or very flattened). In the Hubble sequence E0, E1, E2, ... E7, the number is a function of how flattened the ellipse appears to be, with E0 corresponding to no flattening and E7 to a very elongated ellipse.
