Suggested nameHyoryu-po
Planet typeSmall cold gas planet
It is a small cold gas planet planet with a mass one-thousandth that of K2-308, but two-and-a-half times that of all the other planets in its solar system combined. This planet is named after the deity Hyoryu-po, the demon of chaos.

An observer on Hyoryu-po would therefore see only one sunset every three years.

The polar regions are constantly below 252°K (-21°C).
