NGC 5457 (=
M101 = PGC 50063 = Arp 26), The Pinwheel Galaxy
Discovered (Mar 27, 1781) by Pierre MÚchain
Recorded (without observational verification) by Charles Messier as M101
Also observed (later in 1781) by Charles Messier
Also observed (May 4, 1831) by John Herschel
A magnitude 7.9 spiral galaxy (type SAB(rs)cd?) in Ursa Major (RA 14 03 12.4, Dec +54 20 58)
Historical Identification: Per Dreyer, NGC 5457 (= GC 3770 = JH 1744, M101, 1860 RA 13 58 14, NPD 34 58.6) is "pretty bright, very large, irregularly round, very suddenly much brighter middle with bright small nucleus". The position precesses to RA 14 03 11.5, Dec +54 20 58, essentially dead center on the galaxy listed above and the description fits, so the identification is certain.
Discovery Information: Usually Messier verified discoveries reported to him by MÚchain, and listed both his friend's prior discovery and his own observation. However, at the time of MÚchain's observation of what became M101, the deadline for additions to the 1784 publication of Messier's last Catalog was fast approaching, so he did not verify the observation until later. Messier's description of the object was only recorded (without the date of his observation) in a handwritten note in his personal copy of the printed version. (A similar situation applies to M102 and M103, the last objects recorded by Messier.)
Physical Information: Listed in Halton Arp's Atlas of Peculiar Galaxies as Arp 26, an example of a spiral galaxy with one heavy arm. M101's recessional velocity of only 240 km/sec is too small in comparison to peculiar (non-Hubble-expansion) velocities to provide a reliable estimate of its distance. Redshift-independent distance estimates range from 18 to 29 million light years. Given that and its apparent size of 28 by 26 arcmin (nearly the same size as the full moon), M101 is nearly 200 thousand light years across.

A 14th-magnitude spiral galaxy (type SB(s)bc) in Bo÷tes (RA 14 10 06.9, Dec +17 36 56)
Physical Information: Based on a recessional velocity of 5465 km/sec, PGC 50584 is about 255 million light years away. Given that and its apparent size of 1.2 by 0.8 arcmin, it is about 90 thousand light years across. The galaxy is listed as Arp 79, which is supposed to mean it is a spiral galaxy with a large high surface brightness companion, but there is no sign of such a companion on the corresponding Arp Atlas plate, and the assignment was presumably made merely on the basis of the increased brightness in the star-forming regions on the southwest side of the galaxy.
