Suggested nameSang Gwen
Planet typeWarm planet
Sang Gwen is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. Sang Gwen is orbiting K2-240 every 6 Earth days.

The interior of Sang Gwen is mainly composed of ices and molten metal. It is named after the deity Sang Gwen, the spirit of hate.

As the closest planet to Waif-enr, Sang Gwen has been a prime target for early interplanetary exploration.

Like the other warm planets, Sang Gwen has a ring system, a magnetosphere, and numerous moons, Enshwan being the most famous one.
