Fictional info (?)
Suggested nameYing Myangs
Planet typeLarge cold gas giant
Ying Myangs and Enshwei Fai are large cold gas giants rich in iron. When viewed from Enshwei Fai, Ying Myangs can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. It is named after the deity Ying Myangs, the bringer of the sky.

Like Enshwei Fai, Ying Myangs has been orbiting HIP 65426 for 0.014 billion years, and never moves more than 17 degrees away from HIP 65426.

As seen from HIP 65426, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.

The atmospheric pressure at the planet's surface is 0.28 bar, or roughly the pressure found 1350 m under the oceans of Earth. Ying Myangs's surface is a barren desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.

Liquid water cannot exist on the surface of Ying Myangs due to low atmospheric pressure, which is less than 5 percent of Enshwei Fai's, except at the lowest elevations for limited periods.

Ying Myangs has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Wayfinder flyby missions and later by the Hotchins orbiter.
