M25 is a bright, prominent open cluster. Messier 25 does not have an NGC number because, for an unknown reason, John Herschel did not list it in his General Catalogue. The Danish-Irish astronomer and astronomy historian John Louis Emil Dreyer eventually added M25 to the second Index Catalogue in 1908 using data from the American astronomer Solon Irving Bailey.
