The answer to that question would be Mercury!

Why Is A Year On Mercury So Short?
Well, Mercury orbits the sun faster than any other planet.

A year is defined as the time it takes for a planet to complete its orbit, so an Earth year is different to a Mercurian year (year on Mercury).

Being closer to the sun than Earth, (and therefore having a much smaller orbit), means that Mercury doesn't take as long to travel around the sun as we do.

This means that its year is a lot shorter than ours.

Mercury has days that are 58.7 Earth-days long, and a whole year on Mercury is only 88 days on Earth. This is all to do with how fast the planet orbits the sun.
