Castor Moving Group
The Castor Moving Group is an extensive but physically related group of more than 50 stars, including Castor itself, Vega, Fomalhaut, Alderamin, and Zubenelgenubi, that has a common motion through space. The properties of the group suggest an age for its members of 100 to 300 million years.
