Mercury is closer to the Sun. Venus is hotter anyway.
Venus is nearly twice as far from the Sun as Mercury, yet its surface is far hotter — around 465°C, day and night, pole to pole. A carbon dioxide atmosphere over 90 times denser than Earth's traps heat so effectively that lead would melt on the ground.
Step by step
- Venus's CO2 atmosphere is over 90 times denser than Earth's, and it traps heat ruthlessly.
- The surface holds around 465°C — day and night, pole to pole. Lead would melt there.
- Mercury, far closer to the Sun, can't compete. Greenhouse beats proximity.

Space facts are where the numbers stop making sense. A total eclipse only works because the Sun is 400 times wider than the Moon and 400 times further away. Venus spins backwards, some of the static on an old TV was the Big Bang, and almost all of the universe is missing. Every fact here links to its source.
