graviszban

Graviszban is a fictional planet located in the Kepler-186 system. It is the fifth planet from its star, Kepler-186f, and orbits within the habitable zone. This placement suggests that liquid water could potentially exist on its surface, a key ingredient for life as we know it.

The planet is estimated to be roughly Earth-sized, with a radius of approximately 1.1 times that of Earth. Its mass is also believed to be similar, indicating a rocky composition. Graviszban's atmosphere is thought to be dense enough to provide a stable surface temperature, though its exact composition remains unknown. Scientists speculate it may contain nitrogen and oxygen, similar to Earth's atmosphere.

Observations suggest Graviszban has a rotation period of approximately 30 Earth hours, resulting in a day-night cycle similar to our own. The planet's axial tilt is also believed to be comparable to Earth's, which would lead to distinct seasons. However, these characteristics are based on extrapolations from its orbital parameters and stellar environment. Further research and advanced telescopic observations are needed to confirm these details and to search for potential biosignatures.
