NGC 3500 (= PGC 33277)
Discovered (Apr 2, 1801) by
William Herschel
A 14th-magnitude spiral galaxy (type Sab) in Draco (RA 11 01 52, Dec +75 12 05)
Based on recessional velocity of 7400 km/sec, about 330 million light years away (although another recessional velocity measurement of 3465 km/sec would yield only half (!) that distance). Considered to be a member of the NGC 3523 group of galaxies, in which case the 7000+ km/sec recessional velocity for the other two galaxies suggests that the larger recessional velocity and distance are more accurate. Given that and apparent size of 1.3 by 0.6 arcmins, about 120 thousand light years in diameter. Note: Wikisky incorrectly shows NGC 3465 if NGC 3500 is entered. However, using the PGC 33277 designation shows the correct object.

NGC 3501 (= PGC 33343)
Discovered (Apr 23, 1881) by
Édouard Stephan (11-10)
A 13th-magnitude spiral galaxy (type Scd) in Leo (RA 11 02 47, Dec +17 59 22)
An edge-on spiral galaxy, paired with NGC 3507. Based on recessional velocity of 1130 km/sec, about 50 million light years away, in fair agreement with redshift-independent distance estimates of 65 to 85 million light years. Given that and apparent size of 4.4 by 0.55 arcmins, about 65 thousand light years in diameter.

Given that and apparent size of 3.4 by 2.9 arcmins, about 45 thousand light years in diameter.

NGC 3508 (=
NGC 3505 = IC 2622)
Discovered (Dec 31, 1785) by William Herschel (and later listed as NGC 3508)
Discovered (May 7, 1836) by John Herschel (and later listed as NGC 3505)
Discovered (Jan 14, 1898) by Lewis Swift (and later listed as IC 2622)
The second IC adds (per Howe) "is small, and the star half an arcmin northeast is not involved".

NGC 3510
Discovered (Apr 11, 1785) by
William Herschel

NGC 3511
Discovered (Dec 21, 1786) by
William Herschel
The second IC adds "= V.39. Not found by Innes, while 3513 = V.40 (same description) was well seen (M.N., lix. p. 339)". (The statement = V.39 (William Herschel's list V#39) seems odd, as it was listed as such in the original NGC, and usually such a note would represent a correction.)

NGC 3539 (= PGC 33799)
Discovered (Apr 13, 1831) by
John Herschel
A magnitude 14.6 lenticular galaxy (type S0/a?) in Ursa Major (RA 11 09 08.8, Dec +28 40 21)
Historical Identification: Per Dreyer, NGC 3539 (= GC 2312 = JH 825, 1860 RA 11 01 31, NPD 60 34.5) is "extremely faint". The position precesses to RA 11 09 05.8, Dec +28 40 03, only 0.7 arcmin west southwest of the galaxy listed above and there is nothing else nearby, so the identification is certain.
Physical Information: Based on a recessional velocity of 9705 km/sec, a straightforward calculation indicates that NGC 3539 is about 450 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 435 million light years away at the time the light by which we see it was emitted, about 440 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 1.1 by 0.25 arcmin, the galaxy is about 140 thousand light years across.
