==Daftar dan edisi==
<!--
Edisi pertama mencakup 45 objek bernomor M1 sampai M45. Daftar Total yang diterbitkan oleh Messier akhirnya terdapat 103 objek. Namun dalam perkembangannya daftar tersebut mendapat tambahan dari para astronom lain. Penambahan pertama datang dari Nicolas Camille Flammarion tahun 1921, yang menambahkan M104. M105 M107 ditambahkan oleh Helen Sawyer Hogg pada tahun 1947, M108 dan M109 oleh Owen Gingerich pada tahun 1960, dan M110 oleh Kenneth Glyn Jones pada tahun 1967.<ref>
 
The first edition covered 45 objects numbered [[crab nebula|M1]] to [[Pleiades (star cluster)|M45]]. The total list published by Messier finally contained 103 objects, but the list "got an independent life" by successive additions by other astronomers, motivating the additions by side notes in Messier’s and Mechain’s texts indicating that either of them knew of the objects. The first such addition came from [[Camille Flammarion]] in 1921, who added [[Messier 104]] after finding Messier’s side note in his 1781 edition exemplar of the catalogue. [[Messier 105|M105]] to [[Messier 107|M107]] were added by [[Helen Sawyer Hogg]] in 1947, [[Messier 108|M108]] and [[Messier 109|M109]] by [[Owen Gingerich]] in 1960, and [[Messier 110|M110]] by [[Kenneth Glyn Jones]].<ref>

}}</ref> [[Messier 102|M102]] was observed by Méchain, who communicated his notes to Messier; later, it was admitted by Méchain himself that this object does not exist, and it was simply a re-observation of M101. Some sources mention the galaxy [[NGC 5866]] as an identification for M102, but its description does not fit with Méchain's notes.
