PGC 8161 (with
2MASX J02082216+4128061 = Arp 74)
A 13th-magnitude spiral galaxy (type SAB(rs)c) in Andromeda (RA 02 08 21.4, Dec +41 28 46)

Based on a recessional velocity of 5545 km/sec, PGC 8161 is about 260 million light years away. Given that and its apparent size of 1.5 by 1.5 arcmin, it is about 110 thousand light years across. The bright knot that led to its listing as Arp 74 is 2MASX J02082216+4128061 (shortened to J020822.2+412806 in the image below), but is also referred to for simplicity's sake as Arp 74B.

2MASX J02082216+4128061 (= "Arp 74B", since with
PGC 8161 = Arp 74)
A 16th-magnitude spiral galaxy (type Irr S?) in Andromeda (RA 02 08 22.2, Dec +41 28 06)

Apparent size 0.3 by 0.25 arcmin; nothing else available, but if actually involved with PGC 8161 (which see for images) and also about 260 million light years away, it would be about 20 thousand light years across. (Visual magnitude obtained from Vizier.)
