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 , 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]
