Mantereassa

Mantereassa is a fictional planet located in the Kepler-186 star system, approximately 500 light-years from Earth. It is the fifth and outermost known planet in its system, orbiting a red dwarf star. Mantereassa is classified as a terrestrial planet and is believed to reside within its star's habitable zone, the region where liquid water could potentially exist on the planet's surface.

Observations suggest Mantereassa is slightly larger than Earth, with a radius estimated to be about 1.2 times that of our home planet. Its mass is not precisely known, but it is thought to be substantial enough to retain a significant atmosphere. The planet's atmosphere composition is currently unknown, but its presence is crucial for maintaining surface temperatures suitable for liquid water.

The surface of Mantereassa is thought to be varied, possibly featuring continents, oceans, and mountain ranges, similar to Earth. However, due to the dim nature of its red dwarf star, sunlight on Mantereassa would be significantly less intense than on Earth. The flora, if any exists, would likely have adapted to absorb light at different wavelengths than terrestrial plants. The potential for life on Mantereassa remains a subject of scientific speculation and future research.
