Melotte discovered one asteroid, 676 Melitta, in 1909. The asteroid name is in fact the Attic form of the Greek Melissa, the bee. In that same year Melotte was awarded the Jackson-Gwilt Medal of the Royal Astronomical Society.
In Melotte’s 1915 catalog of deep sky objects he recorded a star cluster in the constellation Coma Berenices which is commonly designated Mel 111. The cluster did not appear in the Messier catalogue or the New General Catalogue because it was not proven to be a true star cluster until 1938.

System (RMS), conducted several on-orbit experiments, and continued the general
shakedown of Shuttle Kennedy Space Center and
flight procedures. Columbia
