IC 450 (= PGC 19756)
Discovered (1890) by William Denning
A 15th-magnitude barred spiral galaxy (type SAB0+) in Camelopardalis (RA 06 52 12, Dec +74 25 37)
Based on recessional velocity of 5640 km/sec, about 250 million light years away. Given that and apparent size of 0.8 by 0.5 arcmins, about 60 thousand light years in diameter. |
