Exoplanet orbiting the yellow giant HD 104985
HD 104985 b, also named Meztli /ˈmɛstli/, is an extrasolar planet approximately 97 parsecs (317 lys) from the Sun. The 198-day period planet orbits the yellow giant star HD 104985 (Tonatiuh) at a distance of 0.78 AU. With a mass 61/3 times Jupiter it is a gas giant.[1][2]
Following its discovery in 2003[1] the planet was designated HD 104985 b. In July 2014 the International Astronomical Union launched NameExoWorlds, 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]
