NGC 4650A
Encyclopedia
NGC 4650A is a polar-ring galaxy
located in the constellation
Centaurus. It should not be confused with the spiral galaxy NGC 4650, which shares almost the same radial distance as NGC 4650A. The real distance between both galaxies is
only about 6 times the optical radius of NGC 4650.
