Tinnoset

Tinnoset is a fictional planet located in the Andromeda galaxy, approximately 2.537 million light-years from Earth. It is the third planet orbiting a G-type main-sequence star known as Solara. Tinnoset is a terrestrial world with a diameter roughly 1.2 times that of Earth, and a surface gravity of 1.1 g. Its atmosphere is primarily composed of nitrogen and oxygen, with trace amounts of argon and carbon dioxide. The planet experiences a moderate axial tilt, resulting in distinct seasons across its surface.

The surface of Tinnoset is characterized by vast oceans covering approximately 70% of its area, interspersed with continents featuring diverse landscapes. These include mountain ranges, extensive forests, arid deserts, and fertile plains. Liquid water is abundant, and the planet supports a rich and varied biosphere. Dominant lifeforms are multicellular organisms with a carbon-based biochemistry, adapted to a wide range of environmental conditions.

Tinnoset is known for its unique geological formations, including crystalline structures that emit a faint bioluminescence during the planet's night cycle. The planet also possesses a strong magnetic field, offering protection from stellar radiation. Its orbital period around Solara is approximately 390 Earth days, and it has one natural satellite, a small moon named Lunara. Tinnoset is a focal point of interest for xenobiologists and planetary scientists due to its Earth-like qualities and the potential for complex life.
