Based on a recessional velocity of 5370 km/sec, PGC 65685 is about 250 million light years away. Given that and its apparent size of 2.1 by 1.7 arcmin, it is about 150 thousand light years across. Used by the de Vaucouleurs Atlas of Galaxy Types as an example of galaxy type (R')SA(r)a.

Note About Classification: The type is taken from the Spitzer Survey of Stellar Structure in Galaxies.

A spectacular result of galactic collision, PGC 65779 (also known as 2ZW096, due to its inclusion in a catalog of galaxy pairs by Fritz Zwicky) is an example of a "starburst" galaxy, in which violent compression of gases due to the physical and gravitational effects of the collision has created huge numbers of hot, bright young stars which are lighting up the galaxy fragments, heating up surrounding gas, and blowing it into intergalactic space. Based on a recessional velocity of 10820 km/sec, a straightforward calculation implies that the pair is about 480 million light years away. However, for such distant objects, we must consider the expansion of the Universe during the nearly half-billion year journey of the light by which we see the object; because of this, the pair was about 15 million light years closer at the time the light was emitted. Given that and their apparent extent of 0.55 by 0.3 arcmin, the pair is about 75 thousand light years across.
