NGC 3800 (= PGC 36197 = (with NGC 3799) Arp 83)
Discovered (Apr 8, 1784) by William Herschel
A 13th-magnitude spiral galaxy (type SAB(rs)b? pec) in Leo (RA 11 40 13.3, Dec +15 20 32)
Based on a recessional velocity of 3310 km/sec, NGC 3800 is about 150 million light years away. Given that and its apparent size of 2.0 by 0.6 arcmin, it is about 90 thousand light years across. Presumably part of an interacting pair, also known as Arp 83. A second radial velocity measurement of 5850 km/sec would put NGC 3800 at a distance of 270 million light years, in which case the "pair" would actually be an optical double, and only appear to be gravitationally interacting; but if anything, NGC 3800 appears to be in front of NGC 3799, so the larger velocity and corresponding distance are probably incorrect. |
