PGC 116500
A magnitude 17(?) spiral galaxy (type Sab?) in
Virgo (RA 12 18 44.4, Dec -02 59 38)
Physical Information: Based on a recessional velocity of 33415 km/sec, a straightforward calculation indicates that PGC 116500 is about 1555 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 1365 to 1370 million light years away at the time the light by which we see it was emitted, about 1440 to 1445 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 0.1 arcmin, the galaxy is about 100 thousand light years across.
