Fictional info (?)
Suggested nameExuha-toh
Planet typeCold gas giant
In English, Exuha-toh is often referred to as the "white planet" because the carbon monoxide prevalent on its surface gives it a deep white appearance that is distinctive among the astronomical bodies visible to the naked eye.

This planet is named after the deity Exuha-toh, the goddess of the underworld.

The hydrogen deuteride (HD) has probably photodissociated, and the free sulfur dioxide has been swept into interplanetary space by the solar wind because of the lack of a nitrogen layer.

There are ongoing investigations assessing the present habitability potential of Exuha-toh, as well as the possibility of extant life.

Because of its fast rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator).

In 3376, images from Wayfinder 3 showed Exuha-toh as an almost featureless planet in visible light, without the cloud bands or storms associated with the other cold gas giants.
