How are the length of a planet year and planet distance from the sun?

A planet year is defined as the time it takes a planet to make one complete revolution in its orbit around the sun. The farther away from the sun a planet is, the larger its orbit. The larger its orbit, the longer (more days) it takes to go around the sun. Thus, the farther away a planet is from the sun, the longer its year will be.
