IC 4450 (= PGC 51939)
Discovered (1895) by Stephane Javelle
A 14th-magnitude spiral galaxy (type Sbc?) in Boötes (RA 14 32 12, Dec +28 33 25)
Based on recessional velocity of 9100 km/sec, about 400 million light years away. Given that and apparent size of 1.1 by 0.5 arcmin, about 125 thousand light years in diameter. |
