In some ways, star clusters are like giant families with thousands of stellar siblings. These stars come from the same origins--a common cloud of gas and dust--and are bound to one another by gravity. Astronomers think that our Sun was born in a star cluster about 4.6 billion years ago that quickly dispersed.
