HD 104985 b, also named Meztli, is an extrasolar planet approximately 97 parsecs (317 lys) from the Sun[1] in the constellation of Camelopardalis.

The 198-day period planet orbits the yellow giant star HD 104985 at a distance of 0.78 AU. With a mass 61/3 times Jupiter it is a gas giant.[2][3]

Following its discovery in 2003[2] 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.[4] The process involved public nomination and voting for the new names.[5] In December 2015, the IAU announced the winning name was Meztli for this planet.[6] The winning name was submitted by the Sociedad Astronomica Urania of Morelos, Mexico. 'Meztli' was the Aztec goddess of the Moon.[7]
