In a distance of about 58 pc it is one of the nearest star clusters known, only the Hyades and the Ursa Major moving cluster appear to be somewhat closer. There are 37 members of the cluster down to 10.5 mag. However, a surprising fact is that the cluster does not contain any fainter stars. They may have dispersed into space since the small cluster with its low total mass can't hold them gravitationally.
