NGC 4650 (= PGC 42891)
Discovered (Jun 26, 1834) by
John Herschel

NGC 4651 (= PGC 42833 =
Arp 189)
Discovered (Dec 30, 1783) by William Herschel
An 11th-magnitude spiral galaxy (type SA(rs)c pec) in Coma Berenices (RA 12 43 42.5, Dec +16 23 37)
NGC 4651's recessional velocity of 805 km/sec is too small to be a reliable indicator of distance, as its peculiar (non-Hubble-expansion) velocity may be a substantial fraction of the measured value. And in fact, the corresponding distance of 37 million light years is considerable smaller than redshift-independent distance estimates of 50 to 100 million light years. Using the larger distance estimates, the galaxy's apparent size of 4.0 by 2.6 arcmins corresponds to 60 to 100 thousand light years (this does not include the extended arms visible in the wide-field image below). Used by the Arp Atlas as an example of a galaxy with narrow filaments.

NGC 4656 (= PGC 42863), The Hockey Stick
Discovered (Mar 20, 1787) by
William Herschel
Also observed (Apr 29, 1827) by John Herschel
A magnitude 10.5 spiral galaxy (type SB(s)m? pec) in Canes Venatici (RA 12 43 58.4, Dec +32 10 21)
Historical Identification: Per Dreyer, NGC 4656 (= GC 3189 = JH 1414 = WH I 176, 1860 RA 12 37 09, NPD 57 04.0) is "a remarkable object, pretty bright, large, very much extended 34, southwestern of 2", the other being NGC 4657. The position precesses to RA 12 43 58.3, within 0.2 arcmin of the center of the galaxy listed above and the description fits, so the identification is certain.
Physical Information: Based on a recessional velocity of 645 km/sec (and H0 = 70 km/sec/Mpc), NGC 4656 is about 30 million light years away, in reasonable agreement with redshift-independent distance estimate of 18 to 24 million light years. Given that and an apparent size of about 8.9 by 1.4 arcmin for the main galaxy and a length of more than 19 arcmin counting the faint northern and southern extensions (from the images below), the main galaxy is about 75 to 80 thousand light years across, and the entire structure spans more than 165 thousand light years. The galaxy is a gravitationally bound companion of NGC 4631, which lies about half a degree to the northwest (and depending upon its distance, could be within half a million light years of its neighbor). Their interaction is probably responsible for the curved end of the galaxy (which is listed as NGC 4657), and its appellation.

NGC 4657
Discovered (Mar 20, 1787) by
William Herschel
A 12th-magnitude star cloud in NGC 4656 (RA 12 44 06.9, Dec +32 12 33)
Per Dreyer, NGC 4657 (= GC 3190 = WH I 177, 1860 RA 12 37 18, NPD 57 00.8) is "remarkable, pretty faint, large, extended about 90, northeastern of 2". The position precesses to RA 12 44 07.1, Dec +32 13 10, about 0.6 arcmin north of the object, which is a region of bright starclouds on the northeastern end of NGC 4656, making that galaxy the 'southwestern of 2' (per its historical description) and NGC 4657 the 'northeastern of 2', confirming its identification. Though treated as a separate nebula when only the brighter portions of NGC 4656 were observable, and still listed as an irregular galaxy in some places (for instance, Steinicke lists it as a peculiar irregular), it is almost certainly a "starburst" region filled with clouds of bright stars as a result of the gravitational interaction of NGC 4656 and NGC 4631, which is less than half a degree to the northwest, and may be less than half a million light years away from NGC 4656. At the 25 to 30 million light years' distance of NGC 4656, the apparent size of NGC 4657 (about 2 by 1 arcmin) corresponds to about 7 or 8 thousand light years.

NGC 4676 (=
IC 819 + 820 = PGC 43062 + 43065 = Arp 242), The Mice
Discovered (Mar 13, 1785) by William Herschel (and later listed as NGC 4676)
Recorded (Mar 20, 1892) by Rudolf Spitaler (and later listed as IC 819 and 820)
A pair of interacting 14th-magnitude galaxies in Coma Berenices
IC 819 = PGC 43062 is a lenticular galaxy (type SB0/a?) at RA 12 46 10.1, Dec +30 43 57
IC 820 = PGC 43065 is a lenticular galaxy (type S0/a?) at RA 12 46 11.2, Dec +30 43 21
Herschel observed the two galaxies as a single "possibly bi-nuclear" nebula, while Spitaler observed them as separate objects, leading Dreyer to give the separate nebulae individual IC listings, despite their already being cataloged as Herschel's NGC listing. The "Mice", so-called because of their long "tails", are a pair of interacting galaxies about 300 million light years away. The two galaxies have recently collided with each other, and will continue to do so again and again (over periods of hundreds of millions of years), until they eventually merge into a single galaxy. In the meantime, their gravitational interaction pulls stars away from each galaxy to form their elongated tails, and compresses the gas and dust between the stars, forming associations and clusters of hot, bright young stars which heat and light up the clouds out of which they just formed. Used by the Arp Atlas as an example of galaxies with the appearance of fission.

NGC 4685 (= PGC 43149)
Discovered (Apr 27, 1785) by
William Herschel
A 13th-magnitude lenticular galaxy (type S0^ pec?) in Coma Berenices (RA 12 47 11.4, Dec +19 27 53)
Based on a recessional velocity of 6790 km/sec, NGC 4685 is about 315 million light years away. Given that and its apparent size of 1.6 by 1.0 arcmin(?), the main body of the galaxy is about 150 thousand light years across. It also has extended "arms" which cover an additional 40 thousand light years both north and south of the central structure. NED lists NGC 4685 as a member of a group (M98j 181). Its distorted appearance is probably due to gravitational interactions with other members of the group.

NGC 4696 (= PGC 43296 = PGC 576860 = PGC 577001)
Discovered (May 7, 1826) by
James Dunlop
Also observed (Jun 5, 1834) by John Herschel
A magnitude 10.4 elliptical galaxy (type E2? pec) in Centaurus (RA 12 48 49.3, Dec -41 18 39)
Historical Identification: Per Dreyer, NGC 4696 (= GC 3226 = JH 3424, Dunlop 510?, 1860 RA 12 41 12, NPD 130 32.5) is "pretty bright, large, round, gradually brighter middle, mottled but not resolved". Discovery Notes: (Some references list this as Dunlop 510, and others as Dunlop 511; I need to do an independent assessment when I complete the historical identification.)
Physical Information: Based on a recessional velocity of 2960 km/sec, NGC 4696 is 135 to 140 million light years away, in good agreement with redshift-independent distance estimates of 80 to 160 million light years. Given that and its apparent size of about 6.8 by 5.4 arcmin (from the images below), it is 270 to 275 thousand light years across. It is listed as a Seyfert galaxy (type Sy 3), and is characterized by unusual spirally arranged filaments extending from its core. These filaments are believed to be associated with infall and subsequent "bubbling" of material caused by a supermassive black hole at the galaxy's center. Their structures are as small as 200 light years, and are thought to be constrained by magnetic fields created by the black hole's interaction with surrounding material. NGC 4696 is the largest and brightest galaxy in the Centaurus Cluster of galaxies.

PGC 43323
Not an NGC object but listed here as a possible companion of
NGC 4696
A magnitude 15.1 spiral galaxy (type Sbc? pec) in Centaurus (RA 12 49 04.1, Dec -41 20 20)
Physical Information: Vr 3470 km/sec, close enough to that of NGC 4696 that it may indeed be in the general neighborhood of NGC 4696. Redshift-independent distance estimates of 85 to 155 million light years, also about the same as for NGC 4696. Possibly a companion of NGC 4696, especially given the distorted shape of its outer regions; but even if only a member of the Centaurus Cluster, there are many other galaxies that it could have interacted with. Apparent size 1.35 by 0.3 arcmin (from the image below).

NGC 4697 (= PGC 43276)
Discovered (Apr 24, 1784) by
William Herschel
A 9th-magnitude elliptical galaxy (type E6) in Virgo (RA 12 48 35.8, Dec -05 48 00)
A member of the Virgo cluster of galaxies. Based on a recessional velocity of 1240 km/sec, NGC 4697 is about 58 million light years away, in good agreement with redshift-independent distance estimates of 30 to 75 million light years. Given that and its apparent size of 7.2 by 4.7 arcmins, the galaxy is about 120 thousand light years across.
