Fictional info (?)
Suggested nameGemu-gyo
Planet typeCold planet
For this reason, scientists often classify Gemu-gyo and Sekyobo-so as "cold planets" to distinguish them from the other planets. This cold planet is named after the deity Gemu-gyo, the bringer of good fortune.

The rotational period and seasonal cycles of Gemu-gyo are likewise similar to those of Earth, as is the tilt that produces the seasons.

The two polar ice caps appear to be made largely of dust.
