Fictional info (?) |
Suggested name | Andasto |
Planet type | Cold planet |
It is a cold planet planet with a mass one-thousandth that of HD 159868, but two-and-a-half times that of all the other planets in its solar system combined. This cold planet is named after the deity Andasto, the god of the underworld.
Like Phaë, Andasto has been orbiting HD 159868 within Drabauti Spon's orbit as an inferior planet, and never moves more than 11 degrees away from HD 159868.
It has the densest atmosphere of the known cold planets, consisting primarily of hydrogen deuteride (HD). Andasto is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. Andasto's surface is a arid desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.
Plans have been proposed for rovers or more complex missions, but they are hindered by Andasto's hazardous precipitation.
There are ongoing investigations assessing the past habitability potential of Andasto, as well as the possibility of extant life.
The Andasto system has a unique configuration among those of the planets because its axis of rotation is tilted sideways, nearly into the plane of its solar orbit. |
