PGC 509 (with PGC 510 = Arp 146)
A 17th-magnitude ring galaxy (type (R)S pec?) in Cetus (RA 00 06 43.8, Dec -06 38 11)
Based on a recessional velocity of 22615 km/sec, a straightforward calculation indicates that PGC 509 is about 1050 million light years away. However, for objects at such distances we should take into account the Universal expansion during the time it took their light to reach us. Doing that shows that the galaxy was about 965 million light years away at the time the light by which we see it was emitted, about 1000 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 0.25 arcmin, the galaxy is about 110 thousand light years across. The appearance of the galaxy and its nearby companion, PGC 510, suggest that the latter galaxy passed through the former in the not too distant past (relative to the time at which we see them), stripping material out of each galaxy, and causing a wave of intense star formation. (For a closer look at a similar system, see IC 298.)

PGC 510 (with PGC 509 = Arp 146)
A 16th-magnitude spiral galaxy (type Sa pec?) in Cetus (RA 00 06 44.8, Dec -06 38 15)
Based on its apparent interaction with PGC 509 (which see for images), PGC 510 must be at about the same distance (of about 965 million light years). Given that and its apparent size of 0.3 by 0.25 arcmin, it is about 85 thousand light years across.

PGC 676
A 14th-magnitude galaxy (type Sbc) in Andromeda (RA 00 09 28.7, Dec +47 21 21)
Based on a recessional velocity of 5155 km/sec, PGC 676 is about 230 million light years away. Given that and its apparent size of 1.2 by 0.5 arcmin, it is about 80 thousand light years across. PGC 676 is listed as a member of Local Galaxy Group 485, which also contains PGC 2 and IC 1525. IC 1525 is also listed as a member of WBL729, a group with an average recessional velocity of about 5020 km/sec which also includes PGC 18 and 73195; so all five galaxies may be physically related. PGC 2, 18 and 73195 and IC 1525 (which see for a wide-field view of the four galaxies) are less than 30 arcmin apart, and if at nearly the same distance from us, may be within a region less than two million light years across; but PGC 676 is quite a bit further away, being about 2 1/2 degrees east of the other group members.

(See NGC 25 for anything else.)
PGC 707
A 15th-(B)magnitude spiral galaxy (type Sb) in Pegasus (RA 00 10 02.0, Dec +28 12 37)
Based on a recessional velocity of 8170 km/sec, PGC 707 is about 365 million light years away. (Strangely, redshift-independent distance estimates only range from 40 to 50 million light years, suggesting that a cataloging error has led to measurements of the wrong object.) Presuming that the recessional velocity is correct, and given its apparent size of 1.0 by 0.9 arcmin, PGC 707 is about 100 thousand light years across. (If the redshift-independent distance estimates were correct, the galaxy would only be about 13 thousand light years across, which seems far too small for a galaxy with its structure.) Based on its recessional velocity and position, PGC 707 is listed as a member of the NGC 22 Group of galaxies, which also includes PGC 687, 762, 791, 816, 896, 941 and 953.

PGC 791
A 15th-(B)magnitude spiral galaxy (type (R')SAB0^+(s)) in Andromeda (RA 00 11 14.2, Dec +28 54 23)
Based on a recessional velocity of 8045 km/sec, PGC 791 is about 360 million light years away, somewhat beyond redshift-independent distance estimates of 270 to 290 million light years. If the larger distance is correct its apparent size of 1.3 by 1.2 arcmin implies that it is about 130 thousand light years across; if the smaller distance is correct it would be about 100 thousand light years across. Based on its recessional velocity, PGC 791 is listed as a member of the NGC 22 Group of galaxies, which also includes PGC 687, 707, 762, 816, 896, 941 and 953.

A magnitude 15(?) spiral galaxy (type SAB(rs)bc?) in Pisces (RA 00 11 26.4, Dec +06 23 30)
Physical Information: An apparent companion of NGC 36, but since its distance is unknown, whether it is a physical companion or (more likely) a more distant galaxy (and therefore an "optical double") is also unknown. Apparent size of about 0.8 by 0.2 arcmin (from the images below).

PGC 800
(= ESO 293-045)
A magnitude 14.3 spiral galaxy (type SBd?) in Phoenix (RA 00 11 24.8, Dec -41 23 54)
Physical Information:
Note About Classification: The Spitzer Survey of Stellar Structure in Galaxies lists this as type S/Im: sp. "sp" indicates a "spindle" (an "edge-on" galaxy), which makes classification more difficult, and "m:" indicates that at least in the infrared it is loosely structured, and between that and the edge-on view, not only the "m" but even whether the galaxy is a spiral or an irregular galaxy is unclear (hence the "S/I"). In visible light, classifications range from SBc to SBdm, though mostly in favor of the "earlier" type; as a result, the type I used for the description line deserves its question mark, and two might not be out of the question.

Based on a recessional velocity of 8040 km/sec, PGC 816 is about 360 million light years away, in good agreement with redshift-independent distance estimates of 345 to 550 million light years. Given that and its apparent size of 0.9 by 0.5 arcmin, it is about 90 thousand light years across. PGC 816 is listed as a member of the NGC 22 Group of galaxies, which also includes PGC 687, 707, 762, 791, 896, 941 and 953.

Based on a recessional velocity of 4505 km/sec, PGC 830 is about 200 million light years away, in good agreement with redshift-independent distance estimates of 170 to 200 million light years. Given that and its apparent size of 1.2 by 0.7 arcmin, it is about 70 thousand light years across.

PGC 889
A 15th-(B)magnitude irregular galaxy (type Im) in Pegasus (RA 00 13 17.7, Dec +17 01 45)
Based on a recessional velocity of 855 km/sec, PGC 889 is about 38 million light years away, in good agreement with a redshift-independent distance estimate of 40 million light years. Given that and its apparent size of 2.4 by 0.3 arcmins, it is about 30 thousand light years across. It is possible that the galaxy is one of an interacting pair, given the nearby object to its southeast; but nothing is known of that object, so at this point that is merely a speculation.

The galaxy is listed as a member of the NGC 23 Group, along with NGC 1 and 26, and PGC 619, 654 and 830. Note: A Wikisky search for PGC 912 shows PGC 12, instead (this is a common Wikisky truncation error); use the position to search for the object.

A 15th-(B)magnitude spiral galaxy (type S0?) in Andromeda (RA 00 14 12.7, Dec +28 32 42)
Based on a recessional velocity of 7140 km/sec, PGC 941 is about 320 million light years away. Given that and its apparent size of 0.55 by 0.5 arcmin, it is about 50 thousand light years across. PGC 941 is listed as a member of the NGC 22 Group of galaxies, which also includes PGC 687, 707, 762, 791, 816, 896 and 953. Note: PGC 941 is not recognized by NED by its PGC number; use CGCG 499-084 for a search. Also, a Wikisky search for PGC 941 shows PGC 41, instead (an all too common truncation error); so use the position to search for the correct object.

PGC 943
A 16th-(B)magnitude galaxy in Cetus (RA 00 14 26, Dec -07 26 34)
Based on recessional velocity of 11165 km/sec, about 500 million light years away. At this distance, the expansion of the Universe during the half billion year light travel time means that the galaxy was about 20 million miles closer, or about 480 million light years away, when the light by which we see it was emitted. Given that and its apparent size of 0.3 by 0.3 arcmin, about 40 thousand light years across. Note: A Wikisky search for PGC 943 shows PGC 43, instead. This is a common Wikisky truncation error, and necessitates a search based on the coordinates.

Note: A Wikisky search for PGC 970 shows PGC 70, instead (an all too common truncation error); so use the position to search for the correct object.

PGC 971
A magnitude 14.5(?) lenticular galaxy (type SB0(s)a? pec) in Cetus (RA 00 14 40.4, Dec -07 17 45)
Physical Information: Based on a recessional velocity of 5360 km/sec (and H0 = 70 km/sec/Mpc), PGC 971 is about 250 million light years away. Given that and its apparent size of about 0.7 by 0.45 arcmin (from the images below), it is about 50 thousand light years across. Since the distance and direction of PGC 971 and 972 are nearly the same, they may be part of the same group of galaxies; but their relatively small size means they would have to be very close to have a significant gravitational effect on each other. Note: A Wikisky search for PGC 971 shows PGC 71, instead. This is a common Wikisky truncation error, and necessitates a search based on the coordinates; but a search for PGC 972 shows the correct object.

PGC 972
A magnitude 15.5(?) lenticular galaxy (type S0(s)a? pec) in Cetus (RA 00 14 41.1, Dec -07 16 47)
Physical Information: Based on a recessional velocity of 5145 km/sec (and H0 = 70 km/sec/Mpc), PGC 972 is about 240 million light years away. Given that and its apparent size of about 0.35 by 0.3 arcmin (from the images below), it is about 25 thousand light years across. Since the distance and direction of PGC 971 and 972 are nearly the same, they may be part of the same group of galaxies; but their relatively small size means they would have to be very close to have a significant gravitational effect on each other.

PGC 977
A magnitude 12.6 double star in Tucana (RA 00 14 49.0, Dec -60 18 59)
Misidentification As A Distant Galaxy: PGC 977 is merely a double star, but is misidentified as a galaxy in both LEDA and NED. LEDA has the correct position for the double star but lists the physical information for the galaxy, while NED has the correct position and physical information for the galaxy (APMUKS(BJ) B001214.36-603524.5, discussed in the following entry), but still misidentifies it as PGC 977. (In the image below the galaxy is shown as J001440.4-601838, corresponding to its J2000 coordinates.)
Truncation Error Note: A Wikisky search for PGC 977 suffers from a common truncation error for objects having a leading 9 in their designation, and shows PGC 77, instead. To see the correct object do a search for NGC 53, which as shown below is near both the double star and the galaxy so often confused with it.

A magnitude 17.5 galaxy (type E/S0??) in Tucana (RA 00 14 40.4, Dec -60 18 38)
Misidentification As PGC 977: As discussed in the entry for PGC 977, the galaxy discussed in this entry is often misidentified as that PGC object, and its physical information is therefore mistakenly attached to the double star that is actually the PGC object.
Physical Information: Based on a recessional velocity of 37300 km/sec, a straightforward calculation indicates that APMUKS(BJ) B001214.36-603524.5 is about 1735 to 1740 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 1505 million light years away at the time the light by which we see it was emitted, about 1595 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 0.18 by 0.13 arcmin (from the image below), the galaxy is about 75 to 80 thousand light years across. The (very uncertain) galaxy type is based on the fact that the galaxy is far brighter in the red and infrared than in the blue and ultraviolet, which is more typical of elliptical and lenticular galaxies than spirals.

PGC 996
A 15th-(B)magnitude spiral galaxy (type S?) in Cetus (RA 00 15 00, Dec -07 15 38)
Based on recessional velocity of 11085 km/sec, about 495 million light years away. At this distance, the expansion of the Universe during the half billion year light travel time means that the galaxy was about 20 million miles closer, or about 475 million light years away, when the light by which we see it was emitted. Given that and apparent size of 0.7 by 0.2 arcmin, about 100 thousand light years across. Note: A Wikisky search for PGC 996 shows PGC 6, instead. This is a common Wikisky truncation error, and necessitates a search based on the coordinates.
