IC 298 (also known as Arp 147 ) is a pair of galaxies in the constellation Whale , approximately 431 million light years from the Milky Way . Part of IC 298 is one of the rare ring galaxies that was created when these two galaxies collided. Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy belongs to the class galaxies with associated rings (Arp catalog) .
The galaxy pair IC 298 was discovered on December 29, 1893 by the French astronomer Stéphane Javelle .
