NGC 12 (= PGC 645)
Discovered (Dec 6, 1790) by William Herschel
Also observed (Oct 16, 1827) by John Herschel
A magnitude 13.1 spiral galaxy (type SAB(rs)bc?) in Pisces (RA 00 08 44.7, Dec +04 36 45)
Historical Identification: Per Dreyer, NGC 12 (= GC 4 = JH 1 = WH III 868, 1860 RA 00 01 34, NPD 86 10.2) is "extremely faint, pretty large, very gradually a little brighter middle". The position precesses to RA 00 08 44.6, Dec +04 36 34, within 0.2 arcmin of the center of the galaxy listed above and well within its outline, so the identification is certain.
Physical Information: Based on a recessional velocity of 3940 km/sec (and H0 = 70 km/sec/Mpc), NGC 12 is about 180 to 185 million light years away, in fair agreement with a single redshift-independent distance estimate of 155 million light years. Given that and its apparent size of about 1.7 by 1.35 arcmin (from the images below), it is about 90 thousand light years across.
