Here's how long it takes each of the 8 planets to orbit the Sun:
* Mercury: 88 Earth days
* Venus: 225 Earth days
* Earth: 365.25 Earth days
* Mars: 687 Earth days
* Jupiter: 11.86 Earth years
* Saturn: 29.46 Earth years
* Uranus: 84 Earth years
* Neptune: 165 Earth years
As you can see, the further a planet is from the Sun, the longer its orbital period (the time it takes to complete one orbit).
