The location of NGC 4650A (circled in blue)

NGC 4650A is a polar-ring[2] lenticular[1] 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.[4]
