What is the hottest planet in the Solar System?
Mercury
Venus
Mars
Jupiter
Venus is by far the hottest planet in the Solar System, with a mean surface temperature of 462 °C, even though Mercury is closer to the Sun. What's interesting, studies have suggested that billions of years ago Venus's atmosphere was much more like Earth's than it is now, and that there may have been substantial quantities of liquid water on the surface.
