You would think that since Venus is slightly smaller, slightly less dense, and a
lot hotter than Earth, that its atmosphere would have boiled off quite a while
ago, yet its atmosphere is much denser and hotter than our own. Even Saturn's
moon Titan has an atmophere denser than our own, though it is slightly cooler,
yet Titan is not much bigger than our own moon. There is a distinct correlation
between atmospheric density and tidal influence. Compared to its surface
gravity, Earth has the highest level of tidal influence, yet proportionately the
lowest atmospheric density of all bodies in the entire solar system. This cannot
be an accident.
