| Suggested name | Tiamne |
| Planet type | Cold planet |
| Tiamne 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. Tiamne is orbiting KMT-2021-BLG-1931 every @ORBITALPERIOD Earth days. It is the second-brightest natural object in the night sky after Tuspsa Iaka, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, rarely, visible to the naked eye in broad daylight.
The planet is named after the deity Tiamne, the spirit of war.
Like Tuspsa Iaka, Tiamne has been orbiting KMT-2021-BLG-1931 for @STARAGE billion years, and never exceeds 20 degrees away from KMT-2021-BLG-1931.
As seen relative to the fixed stars, it rotates on its axis exactly two times for every five revolutions it makes around KMT-2021-BLG-1931.
Tiamne is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. |
