“Why is Venus hotter than Mercury, when Mercury is closer to the sun?”
Venus is hotter than Mercury due to its thick CO2 atmosphere and heat-trapping effects.
Key points
- Venus, though farther from the Sun, reaches about 900°F (480°C) on its surface.
- Mercury's max temperature is around 800°F (430°C) due to almost no atmosphere.
- Venus' dense carbon dioxide atmosphere traps heat, creating a strong greenhouse effect.
- Cloud cover reflects about three-quarters of sunlight, with only ~3% reaching Venus' surface.
- The planet's warmth is sustained by atmospheric processes, not just solar proximity.
