HD 52265 b, formally named Cayahuanca, is a gas giant exoplanet located approximately 98 light-years away[5] in the constellation of Monoceros, orbiting the star HD 52265.
Mean distance between the planet and the star is half that of Earth from the Sun.
This allowed to calculate its true mass, assuming that the planet orbits in the plane of the star's equator.
The name was selected in the NameExoWorlds campaign by El Salvador, during the 100th anniversary of the IAU.
Cayahuanca means "The rock looking at the stars" in the native Nahuat language.
