Compactia

Compactia is a fictional planet located in the Kepler-186 system. It is the fifth and outermost known planet in the system, orbiting a red dwarf star. Compactia is a terrestrial planet, meaning it has a solid surface, and is believed to be roughly the size of Earth. Its orbital period is approximately 130 Earth days.

The planet's atmosphere is thought to be relatively thin, with a composition that is not yet fully understood. Initial observations suggest the presence of nitrogen and carbon dioxide, but further study is required to confirm these findings and detect other gases. Due to its distance from its star, Compactia is likely a cold world, with surface temperatures significantly below freezing for most of its surface.

Despite the frigid conditions, scientists are interested in Compactia due to its location within the habitable zone of its star. While its own internal heat and atmospheric composition would play a significant role in determining its actual temperature, the possibility of liquid water existing on its surface, or beneath it in subsurface oceans, remains a topic of scientific speculation.

Exploration of Compactia is currently limited to remote observation using advanced telescopes. Future missions are being considered to gather more detailed data about its geology, atmosphere, and potential for harboring life. The study of Compactia contributes to our understanding of exoplanets and the conditions necessary for habitability around different types of stars.
