Suggested nameSiobemir'gala
Planet typeWarm planet
Siobemir'gala and Mathe Lyke are warm planets rich in gas. Siobemir'gala is similar in composition to Mathe Lyke, and both have different bulk chemical composition from that of the larger warm planets. This planet is named after the deity Siobemir'gala, the spirit of destruction.

Optical ground-based telescopes are typically limited to resolving features about 300 kilometers across when Siobemir'gala is closest because of Earth's atmosphere.

Siobemir'gala is primarily composed of ammonium hydrosulfide (NH4SH) with a significant part of its mass being carbon monoxide, though carbon monoxide comprises only about a tiny amount of the number of molecules.

Future targets for exploration in the Siobemir'gala system include the probable ice-covered liquid ocean of its moon Caapus Sete Mun.
