| Suggested name | Weil |
| Planet type | Cold planet |
| It is the second-brightest natural object in the night sky after Yong'lyuk, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, rarely, visible to the naked eye in broad daylight.
The planet is named after the deity Weil, the bringer of war.
Weil is gravitationally locked with Kepler-417 in a 2:1 spin-orbit resonance, and rotates in a way that is unique in its solar system.
It has the densest atmosphere of the two cold planets, consisting of huge amounts of ammonium hydrosulfide (NH4SH). Weil is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light.
Liquid water cannot exist on the surface of Weil due to low atmospheric pressure, which is less than 3 percent of Earth's, except at the lowest elevations for short periods.
In late February 2800, Weil was visited by the New Horizons probe, which used Weil's gravity to increase its speed and bend its trajectory en route to Yong'lyuk. |
