rotation (as opposed to orbiting, which describes the earth's movements around the sun)
The imaginary line around which a planet spins is called its axis. It is an invisible line that runs from the planet's north pole to its south pole and determines the direction of rotation.
Venus is the only planet in our solar system that spins clockwise on its axis. This is also known as a retrograde rotation.
Uranus is the planet in our solar system that spins on its side. Its axis of rotation is tilted at a steep angle, causing it to appear as if it is rolling along its orbit around the sun.
The orbit of a planet is the path it follows as it travels around the sun. The axis of a planet is an imaginary line running through its center and around which it rotates. The tilt of a planet's axis relative to its orbit affects its seasons.
A planet completing one full rotation on its axis is called a "day." This is what determines the length of a day on that planet.

Pluto, but its now no longer classed as a planet - its a `Dwarf Planet`
The line is called an axis.

Jupiter spins the third fastest on its axis, with a day lasting about 9.9 hours.
The imaginary line that the Earth spins on is called the axis.
When a planet spins on its axis it is said to rotate. (Think of a top.)
Those are called orbits. A planet's day and night happen as the body spins on its axis.
How long it spins on it's axis
Neptune
The rotational period, or how fast a planet spins on its axis, determines the length of a day on that planet. A faster spin results in shorter days, while a slower spin leads to longer days.
