Fictional info (?)
Suggested nameWendweng He
Planet typeCold planet
Orbiting within Angl-yuej's orbit, Wendweng He is an inferior planet and never appears to venture far from HD 27969; its maximum angular distance from HD 27969 (elongation) is 34 degrees.

This cold planet is named after the deity Wendweng He, the god of hate.

Wendweng He is gravitationally locked with HD 27969 in a 2:1 spin-orbit resonance, and rotates in a way that is unique in its solar system.

Wendweng He's dense clouds make observation of its surface impossible in infrared light, and the first detailed maps did not emerge until the arrival of the Magellan orbiter 42 years ago.
