Fictional info (?)
Suggested nameKeuhyo Myu
Planet typePlanet
Keuhyo Myu is the smallest and innermost planet in its solar system. Orbiting within Sabunpi's orbit, Keuhyo Myu is an inferior planet and never appears to venture far from Kepler-90; its maximum angular distance from Kepler-90 (elongation) is 31 degrees.

The planet is named after the deity Keuhyo Myu, the demon of the sky.

An observer on Keuhyo Myu would therefore see only one summer every two years.

The polar regions are constantly below 225°K (-48°C).

The atmospheric pressure at the planet's surface is 0.001 bar, or roughly the pressure found 1575 m under the oceans of Earth.

Its apparent magnitude reaches -3, which is surpassed only by Sabunpi, Gyonene-epyu, and Kepler-90.

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).
