What is the closest planet to the sun?
Earth
Mars
Mercury
Jupiter
Fact: Mercury is the closest planet to the Sun, orbiting at an average distance of about 36 million miles. It completes one orbit in just 88 Earth days, giving it the shortest year of any planet in our solar system. Mercury spins so slowly that, from a spot on its surface, about 176 Earth days pass between one sunrise and the next. Its sunlit side gets extremely hot, while its night side plunges far below freezing. Venus, the second planet from the Sun, is hotter overall because its thick, carbon dioxide-rich atmosphere traps heat.
