Quick Answer
Mercury has the shortest year in the solar system. It takes just 88 Earth days to orbit the Sun once.
The Full Story
Mercury is the innermost planet in the solar system and therefore completes the fastest orbit around the Sun. Its year lasts only 88 Earth days. Because it moves so quickly in its orbit, Mercury was known to ancient astronomers as the swiftest planet. Its short year is one of the reasons it experiences extreme temperature differences between its day and night sides.
