NGC 660 is a starburst polar ring galaxy classified as SBa/PRG with a surface brightness of 13.8 magnitude, distance is 42 Mly.
NGC 660 is one of only a few polar ring galaxies and contains a super massive star cluster.. The dust band almost perpendicular to the galaxy is probably the remnant of a violent collision between NGC 660 and a metal rich spiral galaxy.
