Part 2 Answer Key
... Star Clusters are multiple star systems bound together by the force of gravity. Star Clusters can be divided into two main groups. One group is called Globular Clusters. They contain many stars and gravity holds them tightly together. They swarm just outside the galaxy and form a halo or bulge. We k ...
