Fictional info (?)
Suggested nameThrymr-mejul
Planet typeTerrestrial
It has the densest atmosphere of all the terrestrials, consisting primarily of methane. It may have had helium oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

The largest moon, Sete Euan Mippaa, has a diameter greater than that of the planet Neptune.
