Venus: The True Hottest Planet

Despite its proximity, Mercury isn't the hottest. Venus holds that title.

Mercury’s Proximity to the Sun

Mercury is the closest planet to the Sun, but its lack of an atmosphere keeps it cooler.

Venus’ Thick Atmosphere

Venus’ dense atmosphere traps heat, acting like a blanket around the planet. It contains clouds of sulphuric acid, reflecting sunlight.

The Greenhouse Effect on Venus

Carbon dioxide-rich atmosphere on Venus creates an extreme greenhouse effect.

Surface Temperatures Compared

Venus reaches 475°C on the surface, hotter than Mercury's maximum of 430°C.

Day and Night on Mercury

Mercury's temperatures drop drastically at night due to lack of atmosphere.

Constant Venus Surface Heat

Unlike Mercury, Venus maintains intense heat day and night.
