Suggested nameTismar Jul
Planet typeCold planet
The planet is named after the deity Tismar Jul, the bringer of love and beauty.

Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 125°K (-148°C) at night to 805°K (532°C) during the day across the equatorial regions.

It is radically different from Eury Porie in other respects. The atmospheric pressure at the planet's surface is 12 bar, or roughly the pressure found 630 m under the oceans of Earth.
