PharEtosi

PharEtosi is a fictional planet located in the Kepler-186 system. It is the fifth planet from its star, Kepler-186f, a red dwarf. PharEtosi is considered to be within the habitable zone of its star, meaning conditions may be suitable for liquid water to exist on its surface. The planet is roughly Earth-sized, with an estimated radius of 1.1 times that of Earth. Its mass is also believed to be similar to Earth's, suggesting a rocky composition.

The atmosphere of PharEtosi is thought to be denser than Earth's, which could help retain heat and shield the surface from stellar radiation. Spectroscopic analysis has suggested the presence of nitrogen and oxygen, though further confirmation is required. Evidence also points to a significant amount of water vapor, indicating a potential for oceans or large bodies of liquid water. The surface temperature is estimated to be around 15 degrees Celsius on average, though this can vary depending on atmospheric conditions and geological activity.

Due to its orbit around a red dwarf star, PharEtosi experiences a different light spectrum than Earth. The light would appear redder and dimmer. The planet's rotation period and axial tilt are currently unknown, making it difficult to predict seasons or day-night cycles. Research into PharEtosi is ongoing, with future missions aiming to gather more detailed information about its geology, atmosphere, and potential for harboring life.
