NGC 4650 A

NGC 4650 A.

NGC 4650 A is a polar-ring lenticular galaxy at a distance of 130 MLY in Centaurus.

NGC 4650 A is only one of 100 known polar- ring galaxies, composed of an old central group of stars and a young ring of stars rotating farther out . These unusual structures are possibility the remnants of collisions from two galaxies in the distant past.

There are numerous background galaxies and two pairs of interacting galaxies. NGC 4650 (left), the large face-on spiral is the largest galaxy in the field.
