Arp 273 is a pair of interacting galaxies, 300 million light years away in the constellation Andromeda. It was first described in the Atlas of Peculiar Galaxies, compiled by Halton Arp in 1966.^[5] The larger of the spiral galaxies, known as UGC 1810, is about five times more massive than the smaller galaxy.^[6] It has a disc that is tidally distorted into a rose-like shape by the gravitational pull of the companion galaxy below it, known as UGC 1813. The smaller galaxy shows distinct signs of active star formation at its nucleus,^[7] and "it is thought that the smaller galaxy has actually passed through the larger one."^[8]
