Euraz

Euraz is a fictional planet located in the fictional Kepler-186 system. Its discovery was announced in 2077 by the International Space Agency, following extensive telescopic observations and subsequent unmanned probe missions. Euraz is the fifth planet from its star, Kepler-186f, a red dwarf star approximately 500 light-years from Earth.

The planet's surface is characterized by vast, shallow oceans of liquid methane and ethane, with scattered continents composed of silicate rock and frozen hydrocarbons. Its atmosphere is primarily composed of nitrogen and methane, with trace amounts of ammonia and other complex organic molecules. Euraz experiences a slow rotation, resulting in long day-night cycles and significant temperature variations across its surface. The average surface temperature is estimated to be around -180 degrees Celsius (-292 degrees Fahrenheit).

Evidence gathered from probe missions suggests the presence of subsurface liquid water oceans, warmed by geothermal activity. This has fueled speculation about the potential for exotic forms of life adapted to extreme cold and high pressure conditions. Further research is planned to investigate these possibilities, including the deployment of specialized submersibles designed to explore the hypothetical subsurface oceans. The Kepler-186 system remains a significant focus for exoplanet research due to the existence of multiple potentially habitable worlds, including Euraz.
