Milky Way Galaxy is a large barred spiral galaxy that is approximately 100,000 light years in diameter, and contains over 400 billion stars. ( : " ENT ") The galaxy is comprised of three major parts: the Azati Prime , which contains a supermassive core black hole called Sagittarius A, the disc, which is the ring of stars and interstellar dust that gives the galaxy its spiral shape, and the halo, which includes many older stars orbiting the core, but outside the disc, of which most are concentrated in massive globular clusters.
