Valnian

Valnian is a fictional planet located in the fictional Valnian star system, approximately 700 light-years from Earth. Its primary star, Valnios, is a G-type main-sequence star, similar to our Sun. The planet itself is roughly 1.2 times the mass of Earth and orbits within Valnios's habitable zone, suggesting the potential for liquid water on its surface.

The atmosphere of Valnian is primarily composed of nitrogen and oxygen, with trace amounts of argon and carbon dioxide. Surface temperatures vary, with equatorial regions experiencing a temperate climate and polar regions covered in ice. Valnian possesses two small, irregular moons.

Initial surveys indicate a diverse range of biomes, including vast oceans, extensive continents with varied topography, and significant atmospheric phenomena. Evidence suggests the presence of microbial life, though no complex or intelligent life forms have been definitively identified to date. Further exploration is ongoing to understand the planet's full geological and biological potential. The Valnian system is considered a candidate for future deep-space exploration missions due to its Earth-like characteristics.
