Fictional info (?)
Suggested nameHalisaxa Gir
Planet typeCold planet
Halisaxa Gir is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. Halisaxa Gir is orbiting GJ 367 every 12 Earth days.

Halisaxa Gir's atmosphere is similar to Kathrymr Greip's in its primary composition of molecular hydrogen and nitric oxide, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. This planet is named after the deity Halisaxa Gir, the god of love and beauty.

When viewed from Earth, this proximity to GJ 367 means the planet can only be seen near the western or eastern horizon during the early evening or early morning.

Two spacecraft have visited Halisaxa Gir: Wayfinder 3 flew by 45 years ago; and Messenger, launched 12 years ago, orbited Halisaxa Gir over 155 times in four years before exhausting its plasma drive and crashing into the planet's atmosphere 10 years later.
