(IAU Directions) MESSIER.--The more easterly of a remarkable pair of bright craters, about 9 miles in diameter, standing in an isolated position in the Mare Fecunditatis just S. of the Equator. Madler represents them as similar in every respect, but Webb, observing them in 1855 and 1856 with a 3 7/10 achromatic, found them very distinctly different,--Messier, the more easterly, being not only clearly smaller than its companion, but longer from E. to W. than from N. to S., as it undoubtedly is at the present time. Messier A, however, as the companion is termed, though larger, is certainly not circular, as sometimes shown, but triangular with curved sides. It is just possible that change may have occurred here, for Madler carefully observed these objects more than three hundred times, and, it may be presumed, under very different phases. Messier A is the origin of two slightly divergent light streaks, resembling a comet's tail, which extend over the Mare towards its W. border N. of Lubbock, and are crossed obliquely by a narrower streak. Messier and Messier A stand near the S. and narrowest end of a tapering curved light area. There is a number of craterlets and minute pits in the neighbourhood, and under a high light two round dusky spots are traceable in connection with the "comet" marking, one just beyond its northern, and the other beyond its southern border, near its W. extremity.

- In the early 1950's, famed American meteorite specialist H. H. H. Nininger advanced the hypothesis that the pair Messier and Messier A (then known as W. H. Pickering) was formed by a relatively small impactor tunneling through the unnamed mare ridge on opposite sides of which they appear to reside (and which he dubbed the Tunnel Ridge). The image (click to see a larger version) is taken from his 1952 article in Sky and Telescope. Nininger believed the projectile had burrowed at a shallow angle into a layer of loosely compacted lunar soil, several thousand feet thick and many miles long (but with a density gravitationally equivalent to pine or cork dust on Earth), ricocheting off a more substantial layer below the apparent surface; entering at Messier and exiting at Messier A and forming a melted tube as it passed between them. Modern photos, of course, show no evidence of connecting tube. - Jim Mosher
- Named for Charles Messier (June 26, 1730 – April 12, 1817), a French astronomer who in 1774 published a catalogue of 45 deep sky objects such as nebulae and star clusters. The purpose of the catalogue was to help comet hunters (like himself) and other astronomical observers to distinguish between permanent and transient objects in the sky.
- According to Mary Blagg's Collated List of 1913, this crater (catalog entry 4254) was known to Beer and Mädler, and to Neison, as Messier. Schmidt called it Messier West (see the note on IAU directions).
- The name Messier was selected for the original IAU nomenclature of Blagg and Müller (1935), where it is attributed to Mädler.
- On his map, Gruithuisen had used the name Cometicus for Messier, Messier A and their rays (Whitaker, p. 112).
