PGC 4035 (=
IC 76 = PGC 143948)
A magnitude 15.6 lenticular galaxy (type S0/a?) in Cetus (RA 01 08 11.7, Dec -04 33 16)
Given the identification with IC 76, see that for anything else.

PGC 4069
A magnitude 15(?) spiral galaxy (type Sab?) in
Andromeda (RA 01 08 46.3, Dec +38 49 01)
Physical Information: Based on a recessional velocity of 10710 km/sec, a straightforward calculation indicates that PGC 4069 is about 500 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 480 million light years away at the time the light by which we see it was emitted, a little over 485 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 0.55 arcmin, the galaxy is about 105 thousand light years across.

PGC 4070 (= PGC 2800925)
A magnitude 15.1 galaxy (type Sb?) in
Cetus (RA 01 08 52.4, Dec -15 25 18)
Historical Misidentification: Often misidentified as IC 80, which see.
Physical Information: Based on a recessional velocity of 16500 km/sec, a straightforward calculation indicates that PGC 4070 is about 770 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 720 million light years away at the time the light by which we see it was emitted, about 740 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 0.4 by 0.2 arcmin, the galaxy is about 80 thousand light years across.

PGC 4071 (= "IC 80A", and with
PGC 4072 = IC 80 = PGC 3325365)
A magnitude 12.9 spiral galaxy (type E/S0?S?) in Cetus (RA 01 08 51.1, Dec -15 24 22)
Given the identification with IC 80, see that for anything else.

PGC 4072 (="IC 80B" = PGC 138321; with
PGC 4071 = IC 80 = PGC 3325365)
A magnitude 14(?) galaxy (type S0?D?) in Cetus (RA 01 08 50.7, Dec -15 24 31)
Given the identification with IC 80, see that for anything else.

PGC 4073
A magnitude 14(?) galaxy (type SAB0/a? pec) in
Sculptor (RA 01 08 46.8, Dec -36 20 40)
Physical Information: Based on a recessional velocity of 6625 km/sec, PGC 4073 is about 310 million light years away. Given that and its apparent size of 0.45 by 0.35 arcmin, it is about 40 thousand light years across.

PGC 4079 (=
IC 78)
A 14th-magnitude spiral galaxy (type SA(rs)a pec) in Cetus (RA 01 08 47.6, Dec -15 50 41)
Given the identification with IC 78, see that for anything else.

PGC 4081
A magnitude 16.5(?) elliptical galaxy (type E0?) in
Cetus (RA 01 08 49.4, Dec -15 24 12)
Physical Information: Based on a recessional velocity of 16165 km/sec, a straightforward calculation indicates that PGC 4081 is about 750 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 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 0.2 by 0.2 arcmin, the galaxy is about 40 thousand light years across.

PGC 4103 (=
IC 82)
A 14th-magnitude spiral galaxy (type Sb?) in Cetus (RA 01 09 05.8, Dec -16 00 01)
Given the identification with IC 82, see that for anything else.

PGC 4116 (=
