Satellite Galaxy
Subject: Physics | Topics:

The satellite galaxy is a galaxy that orbits a greater galaxy due to gravitational attraction. Although a galaxy consists of a lot of objects (such as stars, planets and nebulae) which have been not connected together, it has a new center of bulk, which represents a weighted average of the positions of each component object. This is comparable to how an everyday object has a center of mass that’s the weighted average of the positions of all its component atoms.
