Difference between Andromeda Galaxy and Globular cluster

Andromeda Galaxy vs. Globular cluster

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kiloparsecs (2.5 million light-years) from Earth, and the nearest major galaxy to the Milky Way. A globular cluster is a spherical collection of stars that orbits a galactic core as a satellite.
