Fictional info (?)
Suggested nameYhiz-a
Planet typeHuge cold gas giant
The polar regions are constantly below 261°K (-12°C).

The sinister surface is crawling with friendly but shy terraformed plants, the "Asacusa'b", which feed in deep valleys by consuming something called Gyjete-tiq if they need to. The Asacusa'b are not related to Noriki but have scales and vary in length from 50 to 70 cm. They are able to live at temperatures from 120 to 190°C but are killed by drought which is common near the poles.
