NGC 1650 = PGC 15931)
Discovered (Nov 12, 1885) by Francis Leavenworth
A 13th-magnitude giant elliptical galaxy (type E4+) in Eridanus (RA 04 45 11.4, Dec -15 52 12)
Per Dreyer, NGC 1650 (= Leavenworth list I (#137), 1860 RA 04 38 40, NPD 106 09.5) is "very faint, pretty small, extended 0°, bright middle nucleus". The second IC lists a corrected RA (per Howe) of 04 38 52 and adds "2 others suspected 3 arcmin southeast and northwest, the latter probably 2 extremely faint stars".
Based on recessional velocity of 10790 km/sec, about 480 million light years away. Given that and apparent size of 2.3 by 1.3 arcmin, about 320 thousand light years in diameter. |
