NGC 5150 (= PGC 47169)
Discovered (May 5, 1834) by
John Herschel
A 12th-magnitude spiral galaxy (type SBbc) in Hydra (RA 13 27 36.4, Dec -29 33 45)
Historical Identification:
Physical Information: Based on a recessional velocity of 3885 km/sec, NGC 5150 is about 180 million light years away. It may be a member of a small group with the interacting pair NGC 5152 and 5153, in which case their common distance would be about 190 to 200 million light years. Given that and its apparent size of 1.3 by 1.0 arcmin, NGC 5150 is about 75 thousand light years across..

NGC 5151 (= PGC 47056)
Discovered (May 8, 1826) by
John Herschel
A 14th-magnitude lenticular galaxy (type E/S0 pec) in Coma Berenices (RA 13 26 40.8, Dec +16 52 26)
Historical Identification:
Physical Information: Based on a recessional velocity of 8165 km/sec, NGC 5151 is about 380 million light years away. Given that, the 0.75 by 0.75 arcmin apparent size of its central region corresponds to about 85 thousand light years, while its 1.8+ by 1.4 arcmin outer regions extend across more than 200 thousand light years.

NGC 5152 (= PGC 47187)
Discovered (May 5, 1834) by
John Herschel
A 12th-magnitude spiral galaxy (type SB(s)b pec?) in Hydra (RA 13 27 51.5, Dec -29 37 09)
Historical Identification:
Physical Information: Based on a recessional velocity of 4165 km/sec, NGC 5152 is about 195 million light years away, in poor agreement with a single redshift-independent distance estimate of 285 million light years. However, its obvious interaction with NGC 5153 shows that they must be at about the same distance, and the average of their redshift-independent distance measurements (about 215 million light years) is in good agreement with their recessional velocity distance average of about 200 million light years. The pair is probably part of a small group with NGC 5150, and if so their common distance of about 190 to 200 million light years and its apparent size of 1.9 by 0.7 arcmin implies that NGC 5152 is about 110 thousand light years across.

NGC 5153 (= PGC 47194)
Discovered (May 8, 1834) by
John Herschel
A 12th-magnitude elliptical galaxy (type E1 pec) in Hydra (RA 13 27 54.3, Dec -29 37 04)
Historical Identification:
Physical Information: Based on a recessional velocity of 4320 km/sec, NGC 5153 is about 200 million light years away, in poor agreement with redshift-independent distance estimates of 135 to 155 million light years. However, its obvious interaction with NGC 5152 (which see for images) shows that they must be at about the same distance, and the average of their redshift-independent distance measurements (about 215 million light years) is in good agreement with their recessional velocity distance average of about 200 million light years. The pair is probably part of a small group with NGC 5150, and if so their common distance of about 190 to 200 million light years and its apparent size of 1.5 by 1.3 arcmin implies that NGC 5153 is about 85 thousand light years across.

NGC 5154 (= PGC 47041)
Discovered (May 1, 1785) by
William Herschel
A 14th-magnitude spiral galaxy (type Scd?) in Canes Venatici (RA 13 26 28.6, Dec +36 00 38)
Historical Identification:
Physical Information: Based on a recessional velocity of 5580 km/sec, NGC 5154 is about 260 million light years away. Given that and its apparent size of 1.4 by 1.2 arcmin, it is about 105 thousand light years across. NGC 5154 may be a companion of its nearest apparent neighbor, NGC 5149.

Physical Information:

NGC 5194 (= PGC 47404 =
M51), The Whirlpool Galaxy
(also, with NGC 5195 = Arp 85)

Discovered (Oct 13, 1773) by Charles Messier
Discovered (Jan 5, 1774) by Johann Bode
Recorded (Jan 11, 1774) by Charles Messier as M51
Also observed (Mar 17, 1828) by John Herschel
A magnitude 8.4 spiral galaxy (type SA(s)bc? pec) in Canes Venatici (RA 13 29 52.6, Dec +47 11 44)
Historical Identification: Per Dreyer, NGC 5194 (= GC 3572 = JH 1622, M51, 1860 RA 13 23 58, NPD 42 04.9) is "a magnificent or otherwise interesting object, Great Spiral nebula". The position precesses to RA 13 29 52.5, Dec +47 11 39, practically dead center on the galaxy listed above and the description fits, so the identification is certain.
Physical Information: NGC 5194's recessional velocity of 465 km/sec is too small to provide a reliable distance indication, but happens to provide a relatively accurate result of 22 million light years. Redshift-independent distance estimates have ranged from 19 to 30 million light years, but observations of a 2005 supernova in NGC 5195 slightly lowered the estimated distance to 23 ± 4 million light years. Given that and its apparent size of 11.2 by 6.9 arcmin, the galaxy is about 70 thousand light years across. Its spectacular spiral structure is believed to be due to its interaction with NGC 5195, with which it forms Arp 85. (Note: The history of discovery implies that M51 should apply only to NGC 5195, but it is not uncommon for NGC 5194 to be referred to as M51A and for NGC 5195 to be referred to as M51B, as though they had both discovered by Messier.) NGC has a bright central nucleus, making it a Seyfert galaxy (type Sy 2). An extensive bridge of stars, gas and dust connects M51 with its smaller companion. Clusters of hot, bright young stars, and gases heated by their radiation illuminate the spiral arms, and clearly define them. Thick dust lanes straddle the arms, sweep across the "bridge" and partially obscure the companion. The Whirlpool Galaxy was the first nebula observed to have a spiral structure, by the 3rd Lord Rosse, using the 72-inch Leviathan (the largest telescope in the world for many decades) at Birr Castle in 1845.

NGC 5195 (= PGC 47413, and with
NGC 5194 = Arp 85)
Discovered (Mar 21, 1781) by Pierre Méchain
A 10th-magnitude lenticular galaxy (type SB01 pec) in Canes Venatici (RA 13 29 59.2, Dec +47 16 03)
Historical Identification:
Physical Information: Recessional velocity and redshift-independent distance estimates for NGC 5195 are identical to those of its companion, NGC 5194 (which see for that discussion). In any event their obvious interaction means they share the same distance, in the range of 22 or so million light years. Given that and the 3.0 by 2.5 arcmin apparent size of the brighter core of NGC 5195, it is about 20 thousand light years across; but due to its interaction with NGC 5194, its stars are scattered across a region nearly 6 arcmin across, which corresponds to about 40 thousand light years. (As noted at NGC 5194, NGC 5195 is sometimes referred to as M51B, even though it was not part of his original discovery.)
