Ontahe

Description
Ontahe 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. Tidal effects from Altahe create constant heavy wind. The dust from Altahe is silicate.

Ontahe may not be scanned from orbit or visited, but it is visible from Altahe's surface.
