Fictional info (?)
Suggested nameRyake-ba
Planet typeTerrestrial
Ryake-ba is similar in composition to Hyofu'bako, and both have different bulk chemical composition from that of the larger terrestrials. This terrestrial is named after the deity Ryake-ba, the demon of hate.

Plans have been proposed for rovers or more complex missions, but they are hindered by Ryake-ba's hostile surface conditions.

A prominent result is the "great brown spot", a giant storm that is known to have existed for centuries since it was first observed by radar.

This harsh place is full of harmless and earth-like plants that survive hidden in craters by seeking the somewhat smaller "Nupyawo-cho". Chozapu Raho are similar to the Fumepa Mu, have 2 arms and vary in size from 40 to 80 cm. They are able to withstand temperatures from 60 to 90°C and sometimes the acidic environment.
