Fictional info (?)
Suggested nameMesopehya
Planet typeTerrestrial
Orbiting within Kucho Roshu's orbit, Mesopehya is an inferior planet and never appears to venture far from K2-115; its maximum angular distance from K2-115 (elongation) is 84 degrees.

The planet is named after the deity Mesopehya, the spirit of the sea.

Like Kucho Roshu, Mesopehya has been orbiting K2-115 for 11 billion years, and never moves more than 13 degrees away from K2-115.

Mesopehya is gravitationally locked with K2-115 in a 3:2 spin-orbit resonance, and rotates in a way that is unique in its solar system.

Mesopehya's surface appears quite bruised and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years.

Mesopehya can easily be seen from Kucho Roshu with the naked eye, as can its orangeish coloring.

The Mesopehya system has a unique configuration among those of the planets because its axis of rotation is tilted sideways, nearly into the plane of its solar orbit.

The surface of this inhospitable planet is dangerous because of the friendly but shy and primitive insects, the "Senajo'choka", which survive at the sea by finding nourishment in smaller pray if the weather permits it. They are related to the Chobi-kyo but have 3 eyes and vary in length from 40 to 80 mm. Senajo'choka can thrive at temperatures from 140 to 200°C and predators attacking which is common near the poles.
