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]
