NGC 7600 (= PGC 71029)
Discovered (Sep 10, 1785) by
William Herschel
A 12th-magnitude lenticular galaxy (type E/S0? pec) in Aquarius (RA 23 18 53.8, Dec -07 34 48)
Historical Identification:
Physical Information: Based on a recessional velocity of 3485 km/sec, NGC 7600 is about 160 million light years away. Given that and its apparent size of about 3.5 by 1.5 arcmins, it is about 160 thousand light years across (this does not count the extended halo seen in the wide-field view below).

NGC 7601 (= PGC 71022)
Discovered (Aug 4, 1880) by
Andrew Common (29)
A 14th-magnitude spiral galaxy (type SAB(s)c?) in Pegasus (RA 23 18 47.1, Dec + 09 14 01)
Historical Identification:
Physical Information: Based on a recessional velocity of 8040 km/sec, a straightforward calculation indicates that NGC 7601 is about 375 million light years away. However, for objects at such distances we should take into account the expansion of the Universe during the time it took their light to reach us. Doing that shows that the galaxy was about 365 million light years away at the time the light by which we see it was emitted, about 370 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time). This result is in good agreement with redshift-independent distance estimates of 355 to 380 million years. Given that and its apparent size of 1.2 by 0.9 arcmin, the galaxy is about 125 thousand light years across.

NGC 7602 (= PGC 71019)
Discovered (Nov 3, 1864) by
Albert Marth (565)
A 14th-magnitude lenticular galaxy (type S0/a?) in Pegasus (RA 23 18 43.5, Dec +18 41 56)
Historical Identification:
Physical Information: Based on a recessional velocity of 11795 km/sec, a straightforward calculation indicates that NGC 7602 is about 550 million light years away. However, for objects at such distances, we must account for the expansion of the Universe during the time it took their light to reach us. Doing that shows that the galaxy was about 525 million light years away when the light by which we see it was emitted, about 535 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel-time). Given that and its apparent size of about 0.55 by 0.5 arcmin, NGC 7602 is about 85 thousand light years across.
