WebOpen star clusters are regions a few light years or tens of light years across which contain hundreds or thousands of stars, all of which formed at about the same time, usually within the last few hundred million years. WebIn cases where the stars are known to be at identical distances such as within a star cluster, a color–magnitude diagram is often used to describe the stars of the cluster with a plot in which the vertical axis is the apparent magnitude of the stars.
