Fictional info (?) Suggested name Nejagyu Planet type Cold planet Nejagyu and Tocha are cold planets rich in rock. The planet is named after the deity Nejagyu, the demon of war. Nejagyu is primarily composed of hydrogen with a significant part of its mass being ammonia, though ammonia comprises only about a limited amount of the number of molecules. In late February 1300, Nejagyu was visited by the New Horizons probe, which used Nejagyu's gravity to increase its speed and bend its trajectory en route to Tocha.
