Caldwell 10, also known as NGC 663, is an open cluster of stars in the constellation Cassiopeia, discovered by William Herschel in 1787. It lies roughly 6,850 to 7,200 light-years from Earth and is a rich cluster holding several hundred stars, several of which are young Be-type stars still shedding gas.
