PGC 128413
A magnitude 14.5(?) spiral galaxy (type Sbc?) in
Phoenix (RA 00 11 41.6, Dec -56 55 46)
Physical Information: Based on a recessional velocity of 9310 km/sec, a straightforward calculation indicates that PGC 128413 is about 430 to 435 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 415 to 420 million light years away at the time the light by which we see it was emitted, about 425 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 1.1 by 0.35 arcmin, the galaxy is about 130 to 135 thousand light years across.

PGC 128414
A magnitude 16(?) lenticular galaxy (type S0/a?) in
Phoenix (RA 00 11 26.3, Dec -56 55 02)
Physical Information: Based on a recessional velocity of 9180 km/sec, a straightforward calculation indicates that PGC 128414 is about 425 to 430 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 410 to 415 million light years away at the time the light by which we see it was emitted, about 420 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 0.8 by 0.6 arcmin, the galaxy is about 95 thousand light years across. (Listed in the NED as 2MASXJ00112633-5655018)
