A group of related stars, usually held
together by gravity. Members of a star
cluster are thought to form together from one
large cloud of gas in space. Open clusters
such as the Pleiades contain from a dozen to
many hundreds of young stars, loosely
scattered over several light years. Globular
clusters are larger and much more densely
packed, containing perhaps 100,000 old stars.
