| Suggested name | Zuhyu |
| Planet type | Cold planet |
| In English, Zuhyu is often referred to as the "orange planet" because the neon prevalent on its surface gives it a dark orange appearance that is distinctive among the astronomical bodies visible to the naked eye.
This cold planet is named after the deity Zuhyu, the bringer of chaos.
Zuhyu is gravitationally locked with HD 20003 in a 2:1 spin-orbit resonance, and rotates in a way that is unique in its solar system.
Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Zuhyu's distance from HD 20003 is only about two-thirds (or 36 pct) of its distance at aphelion.
In November 2300, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Zuhyu.
Optical ground-based telescopes are typically limited to resolving features about 300 kilometers across when Zuhyu is closest because of Earth's atmosphere.
In late February 3300, Zuhyu was visited by the New Horizons probe, which used Zuhyu's gravity to increase its speed and bend its trajectory en route to Bemyaga. |
