Discovered (Apr 8, 1793) by William Herschel
A 12th-magnitude barred spiral galaxy (type SBm?) in Ursa Major (RA 10 54 34.8, Dec +56 59 24)
Based on recessional velocity of 1985 km/sec, about 90 million light years away. Given that and apparent size of 1.4 by 1.3 arcmin, about 35 thousand light years across. Probably gravitationally interacting with PGC 32784, the galaxy just to its left (east) in the closeup below. The other galaxy shown in the image, PGC 2554198, is seven times farther away, and only appears close to the pair. |
