Correct Answer - Option 3 :
\(365 \frac{1}{4}\)
The earth has two types of motions, namely rotation, and revolution. Rotation is the movement of the earth on its axis. The movement of the earth around the sun in a fixed path or orbit is called Revolution.
Revolution of the earth:
- The earth revolves around the sun in its orbit is called revolution.
- It takes 365¼ days (one year) to revolve around the sun.
- We consider a year as consisting of 365 days only and ignore six hours for the sake of convenience.
-
Revolution is often used as a synonym for rotation.
- However, in many fields like astronomy and its related subjects, revolution is referred to as an orbital revolution.
- It is used when one body moves around another, while rotation is used to mean the movement around the axis.
- For example, the Moon revolves around the Earth and the Earth revolves around the Sun.
Hence, the Earth takes 365¼ days to rotate around the sun.
