Suggested nameRyapi-kyoga
Planet typeCold planet
Orbiting within Myobya Pyoba's orbit, Ryapi-kyoga is an inferior planet and never appears to venture far from K2-268; its maximum angular distance from K2-268 (elongation) is 58 degrees.

Ryapi-kyoga is the only habitable planet orbiting K2-268 and one of the largest in its solar system. The planet is named after the deity Ryapi-kyoga, the demon of chaos.

Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Ryapi-kyoga's distance from K2-268 is only about two-thirds (or 63 pct) of its distance at aphelion.
