Suggested nameXavytar-yw
Planet typeHot planet
This hot planet is named after the deity Xavytar-yw, the messenger of dreams.

The water vapor has probably photodissociated, and the free carbonyl sulfide has been swept into interplanetary space by the solar wind because of the lack of a ozone layer.

Future targets for exploration in the Xavytar-yw system include the probable ice-covered liquid ocean of its moon Guni'duda.
