    Following its discovery in 2003[1] the planet was designated HD 104985 b. In July 2014 the International Astronomical Union launched a process for giving proper names to certain exoplanets and their host stars.[3] The process involved public nomination and voting for the new names.[4] In December 2015, the IAU announced the winning name was Meztli for this planet.[5] The winning name was submitted by the Sociedad Astronomica Urania of Morelos, Mexico. 'Meztli' was the Aztec goddess of the Moon.[6]
