PGC 106500
A magnitude 16.5(?) spiral galaxy (type Sc?) in
Grus (RA 21 44 09.2, Dec -41 32 14)
Physical Information: Based on a recessional velocity of 21735 km/sec, a straightforward calculation indicates that PGC 106500 is about 1010 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 930 million light years away at the time the light by which we see it was emitted, 960 to 965 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 about 0.25 by 0.15 arcmin, the galaxy is 65 to 70 thousand light years across.
