planets have revoloution times because back before clocks, they used the sun and some odd looking statues placed correctly to tell the times, so therefore by giving a planet a revolution time they could tell what time of day or year it was by looking at the position of the sun.
Different planets have different orbit times around the sun because they are at varying distances from the sun. Planets that are closer to the sun, like Mercury, have shorter orbit times, while planets that are farther away, like Neptune, have longer orbit times due to the gravitational pull of the sun affecting their speed of revolution.

Planets closer to the Sun, like Mercury and Venus, have shorter revolution periods because they have shorter distances to travel around the Sun. Outer planets, such as Neptune and Pluto, have longer revolution periods due to their larger orbits.

The relationship is given by Kepler's Third Law.
It has something to do with the planets' temperature and climate.
The planets revolve around the sun. The moon revolves around Earth.
Two factors that affect a planets revolution are distance from the sun and size.

At about 225,000 years per revolution, that would work out to about 20 times - give or take.
The rotation periods are (in days) Jupiter: 0.41354 Saturn: 0.44401 Uranus: 0.71833 Neptune: 0.67125 Jupiter takes 11.8 yrs to complete one revolution. Saturn takes 29.5 yrs to complete one revolution. Uranus takes 84 yrs to complete one revolution. Neptune takes 164.8 yrs to complete one revolution.

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.
An "orrery" is a mechanical contraption, most no bigger than a desktop, that simulates the planets in their revolution around the sun. More complicated (and expensive) models also simulate the planets' rotation on their axes, and the revolution of some of the planets' satellites around their respective planets.
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.
