Fictional info (?)
Suggested nameHeeumeymir Psa
Planet typeSmall warm gas planet
This small warm gas planet is named after the deity Heeumeymir Psa, the demon of love and beauty.

The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to TOI-836, which reoccurs over the so-called synodic period approximately every 151 days.

Plans have been proposed for rovers or more complex missions, but they are hindered by Heeumeymir Psa's hazardous precipitation.

Liquid water cannot exist on the surface of Heeumeymir Psa due to low atmospheric pressure, which is less than 9 percent of Earth's, except at the lowest elevations for limited periods.
