Rotation of the planets of the solar system
Rotation
Rotation is the movement that a planet makes when it turns on itself.
It is this movement that causes the alternation of day and night. When the face of a planet is oriented towards the Sun, it becomes daylight. When she turns her back to him, it is night.
The period of rotation of a planet is the time it takes it to make a turn on itself.
Each planet has its own rotation speed. Some turn very quickly, while others take several months to complete a single turn on themselves.
The planets generally rotate in the same direction as their revolution.
Venus and Uranus have retrograde rotations because they rotate in the opposite direction.
Comparison with the other planets
In order of increasing rotation period.
* Negative rotations are retrograde rotations
