    How long does it take a year on Mercury?

    • It takes 59 Earth days to make one day (or one full rotation) on Mercury. However, a year on Mercury goes by fast! Because it’s the closest planet to the Sun, it doesn’t take very long to go all the way around. It completes one revolution around the Sun in just 88 Earth days. If you lived on Mercury, you’d have a birthday every three months!
