We are at the perfect distance away so that our planet is burned by the sun, yet, we are still close enough that our planet is supported by it. We also have a thick enough ozone to support life.
All planets turn on their axis. This is called the planet's rotation; one complete rotation is equal to one day on that planet.

A planets rotation is dependent on the total number and direction of ALL the hits that it has taken since it initially formed.

It is called rotation.
Unlike their orbits around the sun - which was inherent in the way the planets were formed - their rotation speeds and axis of rotation is random and is dependent on each planet's history of collisions.
The dominant mode of rotation of planets, where they rotate counterclockwise on their axis as viewed from above the North Pole, is called prograde rotation.
Orbit around another body, rotation around its axis.
An imaginary line which passes through the poles of the planet.

Rotation around the planets central axis.
One complete turn of a planet's axis is known as a "single rotation." This rotation typically takes one day to complete on Earth, causing the cycle of day and night.
