Based on a recessional velocity of 5075 km/sec, PGC 73195 is about 225 million light years away. Given that and its apparent size of 1.4 by 0.9 arcmin, it is about 90 thousand light years across. The galaxy is listed as a member of WBL729, a group with an average recessional velocity of about 5020 km/sec which also includes IC 1525
and PGC 18
. IC 1525 is also listed as a member of Local Galaxy Group 485, which includes PGC 2
; so all five galaxies may be physically related. PGC 2, 18 and 73195 and IC 1525
(which see for a wide-field view of the four galaxies) are less than 30 arcmin apart, and if at nearly the same distance from us, may be within a region less than two million light years across; but PGC 676 is quite a bit further away, being about 2 1/2 degrees east of the other group members. In the images below, the reddish cast below and bluish cast above is due to poor color correction of the DSS mosaic; it is not a real difference in color.
Entries after this (numbering in the millions) were added at various later dates. Little if any effort was made to enter galaxies in any particular order, so in some parts of the revised catalog objects with similar numbers are fairly close together in the sky, but in many cases their positions are relatively random. Over time any given part of the sky might be re-examined several times and new or duplicate entries added to the catalog, making the numbering of objects in the region even more random.
