UGC 2812 known asArp 219,[2] are a pair ofinteracting galaxies located 470 millionlight-years away in theEridanus constellation.[1][3] Both galaxies appeared to be distorted and tangled with each other which suggests their inevitable merging to form anelliptical galaxy.[4] Moreover, they present anear-infrared spectra which could result fromstarbursts.[5] Both objects are part ofAtlas 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]
