Astronomers distinguish between two types of star clusters: open star clusters and globular star clusters. They are classified based on their size, shape, age, number of stars, and location in the galaxy. Learn more about the similarities and differences between the two types of star clusters and classic examples of each that can be seen in the night sky.
