Articles with the Messier number in the title use [[Category:Messier objects|###]], dropping the M prefix, and using only the number. The number should be padded up to 3 digits using zeroes. Articles without the Messier number in the title use [[Category:Messier objects]]. A redirect containing the Messier number should also be added to the ...
Charles Messier added it to his catalogue of nebulous objects (now known as the Messier Catalogue) in March 1781. [8] It is one of the closest and brightest barred spiral galaxies in the sky, and is visible with binoculars. [9] It has an isophotal diameter at about 36.24 kiloparsecs (118,000 light-years).
The Wild Duck Cluster (also known as Messier 11, or NGC 6705) is an open cluster of stars in the constellation Scutum (the Shield). It was discovered by Gottfried Kirch in 1681. [ 3 ] Charles Messier included it in his catalogue of diffuse objects in 1764.
