Suggested name | Jichi Sho |
Planet type | Cold planet |
Jichi Sho is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. Jichi Sho is orbiting Kepler-275 every 36 Earth days.
Jichi Sho is similar in composition to Kufuke Re, and both have different bulk chemical composition from that of the larger cold planets. It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 43°K (-230°C), and has a complex, layered cloud structure with 2H2O thought to make up the lowest clouds, and carbon monoxide the uppermost layer of clouds. The interior of Jichi Sho is mainly composed of ices and rock. The planet is named after the deity Jichi Sho, the messenger of the underworld.
It may have had methane oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
In late February 3200, Jichi Sho was visited by the New Horizons probe, which used Jichi Sho's gravity to increase its speed and bend its trajectory en route to Kufuke Re. |
