| Suggested name | Wengch |
| Planet type | Terrestrial |
| This planet is named after the deity Wengch, the creator of hate.
Wengch's surface appears slightly cratered and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years. 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 75°K (-198°C) at night to 385°K (112°C) during the day across the equatorial regions.
The atmospheric pressure at the planet's surface is 60 bar, or roughly the pressure found 1350 m under the oceans of Erdai. Wengch is by far the hottest planet in its solar system, with a mean surface temperature of 261°K (-12°C).
As the closest planet to Erdai, Wengch has been a prime target for early interplanetary exploration.
Surrounding Wengch is a large planetary ring system and a powerful magnetosphere.
In late February 2300, Wengch was visited by the New Horizons probe, which used Wengch's gravity to increase its speed and bend its trajectory en route to Erdai. |
