Fictional info (?)
Suggested nameYongrwang
Planet typeCold planet
Yongrwang and Jeshweng are cold planets rich in ice. This cold planet is named after the deity Yongrwang, the spirit of prosperity.

It may have had hydrogen oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

The latest probe to visit the planet is Pioneer, which entered into orbit around Yongrwang after a very expensive trip.
