NGC 2550 (= PGC 23604)
Discovered (Sep 7, 1885) by Lewis Swift (2-34)
A 13th-magnitude spiral galaxy (type Sb?) in Camelopardalis (RA 08 24 34, Dec +74 00 44)
Based on recessional velocity of 2270 km/sec, about 100 million light years away, in reasonable agreement with redshift-independent distance estimates of 115 to 120 million light years. Given that and apparent size of 1.0 by 0.4 arcmins, about 30 thousand light years in diameter. |
