Earth takes 1 year to orbit the sun.

Each planet takes a different amount of time to complete one orbit around the sun. This is because:

* Distance from the sun: The farther a planet is from the sun, the longer its orbital path and the longer it takes to complete one orbit.

* Orbital speed: Planets closer to the sun move faster in their orbits.

Here are some examples of orbital periods for other planets:

* Mercury: 88 days

* Venus: 225 days

* Mars: 687 days

* Jupiter: 12 Earth years

* Saturn: 29 Earth years

* Uranus: 84 Earth years

* Neptune: 165 Earth years
