ARP 102 is a pair of interacting galaxies. The two galaxies are designated as ARP 102A and ARP 102B. They were discovered by Halton Arp in 1966.
ARP 102A is a small elliptical galaxy.[3] It is classified at an E0.[4] ARP 102B is an active Seyfert galaxy.[5] It is a spiral galaxy classified as SABb[6] that contains two arms, one of which has been extremely elongated.[7]
