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.

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.

A face-on barred spiral, paired with NGC 3501. Based on recessional velocity of 980 km/sec, about 45 million light years away, in fair agreement with a redshift-independent distance estimate of 65 million light years. Given that and apparent size of 3.4 by 2.9 arcmins, about 45 thousand light years in diameter.

The brightest of three galaxies in the NGC 3523 group (consisting of NGC 3523, 3500, and 3465). Based on recessional velocity of 7165 km/sec, about 320 million light years away. Given that and apparent size of 1.5 by 1.5 arcmin, about 140 thousand light years in diameter.
