NGC 11 (= PGC 642)
Discovered (Oct 24, 1881) by Édouard Stephan
A magnitude 13.7 spiral galaxy (type Sa?) in Andromeda (RA 00 08 42.5, Dec +37 26 52)
Historical Identification: Per Dreyer, NGC 11 (Stephan list XII (#2), 1860 RA 00 01 29, NPD 53 19.9) is "very faint, very small, very little extended, 2 very faint stars involved". The position precesses to RA 00 08 42.4, Dec +37 26 52, right on the galaxy listed above, so the identification is certain.
Historical Notes: Dreyer's description is a reasonable translation, but Stephan states that the nebula is an irregular oval extending southeast to northwest, which is a more accurate description of the appearance. Save for round-off errors the NGC position is identical to Stephan's position.
Physical Information: Based on a recessional velocity of 4390 km/sec (and H0 = 70 km/sec/Mpc), NGC 11 is about 205 million light years away, in fair agreement with redshift-independent distance estimates of 165 to 195 million light years. Given that and its apparent size of about 1.7 by 0.4 arcmin (from the images below), it is about 100 to 105 thousand light years across.
