PGC 67110 (= PGC 189327 = ESO 236-29)
A 15th-magnitude spiral galaxy (type (R)SA(r)a) in
Grus (RA 21 39 25.6, Dec -49 09 37)

Based on a recessional velocity of 15990 km/sec, a straightforward calculation indicates that PGC 67110 is about 745 million light years away. But 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 700 million light years away when the light by which we see it was emitted, about 720 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 0.95 by 0.6 arcmin, it is about 200 thousand light years across. Used by the de Vaucouleurs Atlas of Galaxy Types as an example of galaxy type (R)SA(r)a.
