Object name: ARP010
Arp 10 is in Arp's category Spiral galaxies: Split arm. It is located in Cetus about 400 million light years distant. While it appears to have a companion just to the north that galaxy, 2MASX J02182874+0540079, is over 700 million light years further away (1.15 billion total). But it apparently does have a companion. To me, it looks like a star, even on the SDSS image. It is the starlike object right beside the core to the southwest (lower right). It is identified in NED as ARP 010:[BMV2007] Companion with a redshift that puts it about 420 million light-years away. Arp's comment, "Nucleus off center in ring." I can't say I see the "split arm" that caused Arp to put it in that category. Is it the ring that is more a slight oval coil that doesn't quite overlap? Is it the faint arms at the southeast that seem to go in opposite directions? Or is it something else? Arp doesn't explain.
