[edit] Description

Altahe's surface

Altahe is an exceptional form of planet called a Roche World. Put simply, it is one half of a pair of small and unusually dense terrestrial worlds (Altahe and Ontahe) that orbit each other so closely, they effectively share a single atmosphere. That does not mean one could fly from one to the other, but both have identical atmospheres and dust from one often can be found on the other.

Both worlds share an atmosphere of nitrogen and ethane. The surface is warm, and mainly composed of silica dust and dark basaltic rocks, with extensive deposits of heavy metals and radioactives. Tidal effects from Ontahe create constant heavy wind.

[edit] Lifeforms


These rachni appear regardless of whether or not you allow the Rachni Queen on Noveria to live, as they were sent to Depot Sigma-23 before the lockdown at Peak 15.

[edit] Satellites

Ontahe is strictly speaking the second partner in a dual system, Charon to Altahe's Pluto. Both likely orbit with synchronous rotation to one another; Ontahe is always in the same place in Altahe's sky and always shows the same face.

[edit] Trivia

At the Mako landing site, Ontahe is visible near the horizon. This hints that the Mako has landed far from the equator (where Ontahe would be directly overhead), around one of the arctic circles.
