Fictional info (?)
Suggested nameIjiha Si
Planet typeTerrestrial
In English, Ijiha Si is often referred to as the "red planet" because the 2H2O prevalent on its surface gives it a scary red appearance that is distinctive among the astronomical bodies visible to the naked eye.

It is named after the deity Ijiha Si, the demon of destruction.

The polar regions are constantly below 171°K (-102°C).

Two spacecraft have visited Ijiha Si: Daedalus 4 flew by 21 years ago; and Messenger, launched 20 years ago, orbited Ijiha Si over 80 times in four years before exhausting its pwoer source and crashing into the planet's atmosphere 4 years later.

Liquid water cannot exist on the surface of Ijiha Si due to low atmospheric pressure, which is less than 8 percent of Earth's, except at the highest elevations for short periods.
