mercury
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.

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.

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 farther it is from the sun the longer its period of revolution (its "year").
