Fictional info (?)
Suggested nameRyochwang
Planet typeHot gas giant
It is the second-brightest natural object in the night sky after Zhyin-m, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, sometimes, visible to the naked eye in broad daylight.

The planet is named after the deity Ryochwang, the demon of love and beauty.

Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 95°K (-178°C) at night to 1225°K (952°C) during the day across the equatorial regions.

The smooth Borealis basin in the northern hemisphere covers 28 percent of the planet and may be a giant impact feature.
