NGC 6410
Recorded (May 2, 1887) by Lewis Swift (6-93)

NGC 6411
Discovered (Oct 27, 1861) by Heinrich d'Arrest
NGC 6412 (= Arp 38 = PGC 60393)
Discovered (Dec 12, 1797) by William Herschel
A 12th-magnitude spiral galaxy (type SA(s)c) in Draco (RA 17 29 36.9, Dec +75 42 17)
The galaxy's Arp classification is a spiral galaxy with faint companions, but it appears that the "companions" are simply bright star clouds scattered along its somewhat chaotic arms. Based on a recessional velocity of 1315 km/sec, NGC 6412 is about 60 million light years away, in fair agreement with a redshift-independent distance estimate of 75 million light years. Given that and its apparent size of 2.6 by 2.2 arcmin, it is about 45 thousand light years across. |
