* Star Clusters: Astronomers typically use terms like "star cluster" or "open cluster" to describe groups of stars. These clusters can range in size from a few dozen to thousands of stars.
* No Strict Size Limits: There aren't hard and fast rules on how many stars must be in a cluster to qualify for a specific name. The number of stars in a cluster is just one factor that astronomers use to classify them.
* Other Factors: Other factors that astronomers consider when classifying star clusters include their age, density, and distribution of stars.
Examples of star clusters:
* The Pleiades (M45): This famous open cluster contains about 1,000 stars.
* The Hyades: This open cluster is the closest star cluster to our Sun, containing about 100 stars.
So, while there isn't a specific name for a group of stars up to 1,000, you can generally refer to them as a star cluster or an open cluster.
