Galaxy in the constellation Cetus
PGC 2456 known asKAZ 364 andJO201 , is aspiral galaxy located in the constellation ofCetus . It is located 617 millionlight-years away from theSolar System .[ 1] Holmberg 15A .[ 2]
PGC 2456 contains anactive galactic nucleus .[ 3] radio galaxy ,[ 4] 10 M ⊙ .[ 5]
PGC 2456 is considered ajellyfish galaxy due to the fact the tendrils are seen drifting downwards from its core.[ 6] [ 7] star formation in its tendrils and is the Ultraviolet-brightest cluster galaxy in Abell 85.[ 8] [ 9]
Such jellyfish galaxies are formed when galaxies like PGC 2456, moves through high speeds across thegalaxy clusters , causing ram pressure to strip gas. According to studies, researchers estimated PGC 2456 might have lost about 50% of its mass when undergoingram-pressure stripping .[ 10]
