IC 650 (= PGC 170094)
Discovered (Apr 21, 1892) by Stephane Javelle (186)
A 15th-magnitude galaxy (type IrrS?) in Hydra (RA 10 50 41, Dec -13 26 31)
Based on recessional velocity of 8105 km/sec, about 360 million light years away. Given that and apparent size of 0.9 by 0.7 arcmins, about 95 thousand light years in diameter. |
