Theoriaansa 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. Theoriaansa is classified as a terrestrial planet and is believed to reside within its star's habitable zone, the region where conditions might be suitable for liquid water to exist on the surface.
Early telescopic observations suggest Theoriaansa is slightly larger than Earth, with an estimated radius of 1.2
