IC 3900 (= PGC 44068 = PGC 1802312)
Discovered (Jun 25, 1903) by Stephane Javelle (1228)
A magnitude 14.0 lenticular galaxy (type SB0?) in Coma Berenices (RA 12 55 41.2, Dec +27 15 05)
Based on a recessional velocity of 7115 km/sec, IC 3900 is about 330 million light years away. Given that and its apparent size of 0.95 by 0.55 arcmin, it is about 90 thousand light years across.
