PGC 73652
A magnitude 16.4 lenticular galaxy (type S0?) in
Cetus (RA 01 08 41.7, Dec -15 23 44)
Physical Information: (Referred to in NED as 2MASXJ01084173-1523438) Based on a recessional velocity of 15085 km/sec, a straightforward calculation indicates that PGC 73652 is about 705 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 660 million light years away at the time the light by which we see it was emitted, about 680 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 0.3 by 0.15 arcmin, the galaxy is about 55 thousand light years across.

PGC 73653 (=
IC 77)
A magnitude 14.9 lenticular galaxy (type S0?) in Cetus (RA 01 08 43.7, Dec -15 25 15)

PGC 73654
A magnitude 16.4 lenticular galaxy (type S0?) in
Cetus (RA 01 08 45.7, Dec -15 26 25)
Physical Information: (Referred to in NED as 2MASX J01084574-1526258) Based on a recessional velocity of 15350 km/sec, a straightforward calculation indicates that PGC 73654 is about 715 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 675 million light years away at the time the light by which we see it was emitted, about 690 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 0.2 by 0.15 arcmin, the galaxy is about 40 thousand light years across.

PGC 73655
A magnitude 16(?) spiral galaxy (type Sbc?) in
Cetus (RA 01 08 47.1, Dec -15 06 22)
Physical Information: Apparent size 0.5 by 0.1 arcmin, but nothing is known about the galaxy's distance, so nothing is known about its physical size either.

PGC 73656 (= PGC 3084856)
A magnitude 15.3 spiral galaxy (type Sa?) in
Cetus (RA 01 08 47.8, Dec -15 26 17)
Physical Information: (Listed in NED as 2MASXJ01084781-1526178) Based on a recessional velocity of 16965 km/sec, a straightforward calculation indicates that PGC 73656 is about 790 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 740 million light years away at the time the light by which we see it was emitted, about 760 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 0.35 by 0.25 arcmin, the galaxy is about 75 thousand light years across.

PGC 73657
A magnitude 15.3 spiral galaxy (type (R)Sa?) in
Cetus (RA 01 08 48.6, Dec -15 41 40)
Physical Information: Based on a recessional velocity of 16825 km/sec, a straightforward calculation indicates that PGC 73657 is about 785 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 735 million light years away at the time the light by which we see it was emitted, about 755 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 0.75 by 0.45 arcmin, the galaxy is about 160 thousand light years across.

PGC 73658
A magnitude 16.4 lenticular galaxy (type E/S0?) in
Cetus (RA 01 08 48.8, Dec -15 24 35)
Physical Information: (Listed in NED as 2MASXJ01084885-1524358) Based on a recessional velocity of 16670 km/sec, a straightforward calculation indicates that PGC 73658 is about 775 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 725 million light years away at the time the light by which we see it was emitted, about 745 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 0.15 by 0.15 arcmin, the galaxy is about 30 thousand light years across.

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 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 0.25 by 0.2 arcmin, the galaxy is about 50 thousand light years across.

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 715 million light years away at the time the light by which we see it was emitted, about 735 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time).
