PGC 95382
A magnitude 16(?) lenticular galaxy (type E/S0?) in
Phoenix (RA 00 11 19.8, Dec -56 57 05)
Designation Problems: NED does not recognize the LEDA designation of PGC 95382; instead, it lists this object as 2MASXJ00111972-5657065.
Physical Information: Based on a recessional velocity of 9015 km/sec (and H0 = 70 km/sec/Mpc), a straightforward calculation indicates that PGC 95382 is about 420 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 405 million light years away at the time the light by which we see it was emitted, about 410 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 0.45 by 0.35 arcmin (from the images shown below), the galaxy is about 50 to 55 thousand light years across. Although apparently close to NGC 37, the difference of about 760 km/sec in the two galaxies' recessional velocities means that either PGC 95382 is a foreground galaxy, or in the unlikely event that they are close to each other, they will pass by each other in an astronomically short time scale.
