science π₯ Venus is hotter than Mercury, here's why
Venus is significantly hotter than Mercury despite orbiting farther from the Sun. This is because Venus boasts a surface temperature of 900 degrees Fahrenheit (480 degrees Celsius). Meanwhile, Mercury reaches a high of 800 F (430 C) while being closer to the star. The extreme heat on Venus is primarily caused by a runaway greenhouse effect in its atmosphere. Scientists are studying this atmospheric condition to better understand planetary climates.
