Suggested nameDyanwyong
Planet typeCold planet
The planet is named after the deity Dyanwyong, the spirit of the sky.

Two spacecraft have visited Dyanwyong: Daedalus 9 flew by 27 years ago; and Messenger, launched 15 years ago, orbited Dyanwyong over 175 times in four years before exhausting its plasma drive and crashing into the planet's surface 8 years later.

Its apparent magnitude reaches -3, which is surpassed only by Twen, Gyong'pan, and Kepler-731.
