PGC 129500

PGC 129501
A magnitude 15(?) spiral galaxy (type Sbc? pec) in
Horologium (RA 03 50 19.0, Dec -47 47 04)
Physical Information: Based on a recessional velocity of 16170 km/sec, a straightforward calculation indicates that PGC 129501 is about 755 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 705 to 710 million light years away at the time the light by which we see it was emitted, about 725 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 0.5 by 0.45 arcmin, the galaxy is about 100 to 105 thousand light years across. (Listed in the NED as 2MASXJ03501899-4747063)
