Why Venus Could Doom 'Habitable' Exoplanets

Venus’s fate may have come down from its distance from the sun. The exact distances of the Venus zone are based on how much radiation is being emitted from the system’s star. But, regardless of how exactly far it is—the inner edge of the Venus zone is how close a Venus-like planet can get before its stars radiation completely strips way its atmosphere. Venus also has extra gasses that causes rising temperatures and evaporating oceans. This eventually creates a positive feedback loop that ends with a superhot world and no oceans. This especially highlights the importance of a planets distance to its star for habitability.
