Arp 319

Pegasus
Category: Groups of galaxies

Stephans quintet. Hickson 92. One of the most famous multiple systems. It can easily be seen with a 17,5" telescope. Spiral arms and bridging needs photograhy to be clearly seen. The lower left galaxy has only 1/8 of the redshift of the others, and is believed to be much closer to us than the other four galaxies. 

Redshift (group) is 0.0215 (6446km/s)
