Despite its proximity, Mercury isn't the hottest. Venus holds that title.
Mercury is the closest planet to the Sun, but its lack of an atmosphere keeps it cooler.
Venus’ dense atmosphere traps heat, acting like a blanket around the planet. It contains clouds of sulphuric acid, reflecting sunlight.
Carbon dioxide-rich atmosphere on Venus creates an extreme greenhouse effect.
Venus reaches 475°C on the surface, hotter than Mercury's maximum of 430°C.
Mercury's temperatures drop drastically at night due to lack of atmosphere.
Unlike Mercury, Venus maintains intense heat day and night.
Venus teaches us about planetary climates and the potential effects of the greenhouse effect.
