Jiryote Ra is the oldest planet known belonging to K2-282 and one of the smallest in its solar system. This planet is named after the deity Jiryote Ra, the bringer of chaos.

Jiryote Ra is primarily composed of xenon with a significant part of its mass being hydrogen chloride, though hydrogen chloride comprises only about a small amount of the number of molecules.

The latest probe to visit the planet is Juno, which entered into orbit around Jiryote Ra after a tricky journey.
