Revolution
Planet movement around the Sun is described as revolution. Let's break down the concept:
- Definition: Revolution is the orbital motion of a planet around the Sun in a specific path or trajectory. This movement is responsible for the change in seasons and the varying lengths of days throughout the year.
- Key Points:
- The planet follows an elliptical orbit around the Sun, with the Sun located at one of the foci of the ellipse.
- The time taken by a planet to complete one revolution around the Sun is known as its orbital period or year.
- Each planet has a unique orbital period depending on its distance from the Sun and its orbital speed.
- The revolution of a planet also affects its position in relation to the Sun, leading to the occurrence of solstices and equinoxes.
- Comparison with Rotation: Rotation, on the other hand, refers to the spinning of a planet around its axis. While rotation causes day and night cycles on a planet, revolution determines the length of a year and the seasonal changes.
Understanding the concept of revolution is crucial in studying the motion of planets in the solar system and the astronomical phenomena that result from this movement.

When the earth moves on its axis and as well as moves around the sun in a fixed orbit is called revolution.
The time taken for the earth in one revolution is mainly 365 days.
