Fictional info (?)
Suggested nameCalcehy
Planet typeHuge cold gas giant
This huge cold gas giant is named after the deity Calcehy, the demon of war.

Because of its rapid rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). A prominent result is the "great gray spot", a giant storm that is known to have existed for centuries since it was first observed by radar.
