NGC 4339
Discovered (Apr 13, 1784) by William Herschel
NGC 4340 (= PGC 40245)
Discovered (Mar 21, 1784) by William Herschel
An 11th-magnitude barred spiral galaxy (type SB(r)0) in Coma Berenices (RA 12 23 35.2, Dec +16 43 22)
Based on a recessional velocity of 950 km/sec, NGC 4340 is about 45 million light years away, in fair agreement with redshift-independent distance estimates of 55 to 65 million light years, which better agree with the distance of its companion. (The galaxy is generally thought to paired with 55 million light year distant NGC 4350.) Adopting a distance of 55 million light years, the galaxy's apparent size of 3.5 by 2.8 arcmin implies that it is about 55 thousand light years across. |
