PGC 1228197 known as WINGS J211347.41+022834.9 and JO206, is a large spiral galaxy located 700 million light-years away towards the constellation of Aquarius.[1][2] The galaxy is estimated to be at least 160,000 thousand light-years in diameter, making it somehow bigger than the Milky Way. With a radial velocity of 15,200 kilometers per second, it is slowly drifting away. It is classified as a jellyfish galaxy, mainly due to interactions from other galaxies, causing it to run into intracluster medium and stripping the gas from it, which causes long galactic tendrils of stars.[3][4] It has an active galactic nucleus according to SIMBAD.[2]
