Castor Moving Group

The Castor - motion cluster is a star association, which consists of a number of stars, all of which have approximately the same speed and a common origin come from. The stars that were identified as part of the group, are Castor, Fomalhaut, Vega, α Cephei and α Librae, all of which have a similar age.

Findings and Components

The Castor - motion pile was first proposed by JP Anosova and VV Orlov in 1990. Anosova and Orlov beat the original 15 members present as part of the group. A recent study of B. Barrado y Navascues recognizes 16 members, but also points to persisting uncertainties.
