NGC 7 (= PGC 627)
Discovered (Sep 27, 1834) by John Herschel
A magnitude 13.9 spiral galaxy (type SB(s)c?) in Sculptor (RA 00 08 20.8, Dec -29 54 56)
Historical Identification: Per Dreyer, NGC 7 (= GC 2 = JH 4014, 1860 RA 00 01 14, NPD 120 41.2) is "extremely faint, considerably large, much extended, very gradually very little brighter middle". The position precesses to RA 00 08 22.0, Dec -29 54 26, only 0.7 arcmin northeast of the center of the galaxy listed above and within its northern outline, so the identification is certain.
Historical Note: Save for round-off errors in the position, the NGC entry is identical to the GC entry.
Physical Information: Based on a recessional velocity of 1495 km/sec (and H0 = 70 km/sec/Mpc), NGC 7 is about 70 million light years away, in good agreement with redshift-independent distance estimates of 65 to 75 million light years. Given that and its apparent size of about 2.4 by 0.45 arcmin (from the images below), it is about 45 to 50 thousand light years across.
