A planets period or revolution, the time taken to orbit its star, is dependant on its mass, the stars mass and the distance between the two. See Kepler's laws of planetary motion for further information.
The planets are not all the same distance from the Sun, which determines how far they have to travel, and how fast they are moving. Planets farther from the Sun have much longer orbits and are not moving as quickly. So their period of revolution (year) is longer.

The period of a planet's revolution is the time that it takes to complete one revolution around its axis of rotation relative to the background stars (also known as rotation period).
The revolution period of planets is a bit random but only the most massive planets have a gravity field strong enough for them to rotate quickly without flying apart. So the fastest rotator is also the biggest, Jupiter at 9 hr 55 m. Comment : Assuming the questioner was using the word "revolution" correctly, this question is about the orbital periods of the planets. The answer then is: The nearer a planet is to the Sun the shorter its revolution period.
Hi Venus is the only planet that has the revolution period closest to that of the Earth. Venus with a revolution time of 224.7 Earth days. Venus is the brightest of all the planets in the solar system and is known as the Earth's twin sister due to the similarity between the two planets in terms of Size, mass etc.
The planets are not all the same distance from the Sun, which determines how far they have to travel, and how fast they are moving. Planets farther from the Sun have much longer orbits and are not moving as quickly. So their period of revolution (year) is longer.
It's the distance from the Sun that determines the period of revolution. The period squared is proportional to the distance cubed, so if it is at a distance of 4 astronomical units, it takes 8 years to go round.
The farther it is from the sun the longer its period of revolution (its "year").
They all have a difference because they all are not the same distance from the Sun, which determines how far they have to travel, and how fast they are moving. Planets farther from the Sun have much longer orbits and are not moving as quickly. So their period of revolution (year) is longer.
