Abell 262 is a galaxy cluster in the Abell catalogue. It is part of the Perseus–Pisces Supercluster, one of the largest known structures in the universe.[4] Although its central galaxy, NGC 708, is a giant cD galaxy, most of its bright galaxies are spirals, which is unusual for a galaxy cluster.[4] With approximately 200 members it is a comparatively small cluster.[5]
