Describe the three types of galaxies. What is the name of the galaxy Earth is part of and what type of galaxy is it?

(simple and keep it short)

1 answer

The three main types of galaxies are:

  1. Spiral Galaxies: These have a flat, rotating disk with spiral arms that contain stars, gas, and dust, like the Milky Way.

  2. Elliptical Galaxies: These are oval-shaped and consist mostly of older stars with little gas and dust. They range from nearly spherical to more stretched out.

  3. Irregular Galaxies: These do not have a distinct shape and can appear chaotic, often containing a mix of young and old stars.

Earth is part of the Milky Way Galaxy, which is a spiral galaxy.
