Based on a recessional velocity of 9650 km/sec, PGC 26124 is about 450 million light years away. Given that and its apparent size of 0.7 by 0.55 arcmin, it is about 90 thousand light years across.

Based on a recessional velocity of 11920 km/sec, a straightforward calculation indicates that PGC 26132 is about 555 million light years away. However, for objects at such distances we should take into account the Universal expansion during the time it took their light to reach us. Doing that shows that the galaxy was about 525 million light years away at the time 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 0.8 by 0.5 arcmin, PGC 26132 is about 120 thousand light years across.

(Listed in NED as UGC 04881 NED02.) Even without its recessional velocity, which at 11780 km/sec is essentially the same as that of its companion, PGC 26132 (which see for images), the interaction between it and the other galaxy would imply that it is at about the same distance (of 525 million light years). Given that and its apparent size of 0.2 by 0.15 arcmin, PGC 3098124 is about 30 thousand light years across. Note: The only listed magnitude is for radio wavelengths, so the optical magnitude is based on a comparison of its appearance to that of its companion and nearby galaxies of known brightness. The actual value could be as much as a magnitude fainter.
