UGC 224 known as Arp 201,[1] are a pair of interacting galaxies located 860 million light-years in the constellation of Pisces.[2]
Details
The pair comprises UGC 224 NED01 (PGC 1504)[3] a type E galaxy and UGC NED02 (PGC 1503)[4] a S0 galaxy, with a separation of 0.4'.[5] They are slowly gravitationally drifting towards each other and are in the first phase of merging.[6] A faint plume is seen around the pair[7] hinting they are possibly undergoing intense star formation.[6] The galaxies have an approximate diameter of 140,000 thousand light-years, which means they are slightly bigger compared to the Milky Way. Both galaxies belong to Atlas of Peculiar Galaxies, where they belong to a class of galaxies with material ejecting from their nuclei.
