UGC 2812 known as Arp 219,[2] are a pair of interacting galaxies located 470 million light-years away in the Eridanus constellation.[1][3] Both galaxies appeared to be distorted and tangled with each other which suggests their inevitable merging to form an elliptical galaxy.[4] Moreover, they present a near-infrared spectra which could result from starbursts.[5] Both objects are part of Atlas of Peculiar galaxies, where they are categorized under galaxies that have adjacent loops which are a manifestation of structures that were formed by gravitational interactions.[6]
