PGC 1228197known asWINGS J211347.41+022834.9andJO206,is a largespiral galaxylocated 700 millionlight-yearsaway towards the constellation ofAquarius.[1][2]The galaxy is estimated to be at least 160,000 light-years in diameter, making it somehow bigger than theMilky Way.With a radial velocity of 15,200 kilometers per second, it is slowly drifting away. It is classified as ajellyfish galaxy,mainly due to interactions from other galaxies, causing it to run intointracluster mediumand stripping the gas from it, which causes long galactic tendrils of stars.[3][4]It has anactive galactic nucleusaccording toSIMBAD.[2]
