Proberna

Proberna is a fictional planet located in the Andromeda Galaxy. It is known for its unique geological formations and a highly unusual atmosphere. The planet's surface is characterized by vast, crystalline plains that shimmer under the light of its twin suns. These plains are interspersed with deep canyons, some of which are rumored to extend miles into the planet's crust. The atmosphere of Proberna is composed primarily of noble gases, with trace amounts of exotic elements that give it a distinctive iridescent quality. This atmospheric composition makes it unsuitable for most known forms of life, though speculative theories suggest the existence of extremophile organisms adapted to its harsh conditions.

The planet's gravity is approximately 0.8 Earth standard, and its orbital period around its binary star system is relatively short, leading to rapid seasonal changes. Proberna has a single, large moon named Lumina, which casts a soft, ethereal glow on the planet's surface during its nocturnal cycle. Due to its remote location and the challenging environmental factors, Proberna has seen limited exploration by interstellar civilizations. However, its unique properties have made it a subject of interest for xenogeologists and atmospheric scientists. Further research is ongoing to understand the full extent of Proberna's geological and atmospheric phenomena.
