๐ฌ Think about it
The Earth does not just spin in one spot. Like a runner on a track, it travels a huge loop around the Sun, taking a whole year for one lap. This second motion explains the changing night sky and the seasons. Let us explore revolution.
The Earth revolving around the Sun on its orbit.
What is the revolution of the Earth?
- Revolution is the motion of an object around another object.
- The Earth revolves around the Sun while it also spins.
- The path it takes is called its orbit.
- One revolution takes about 365 days and 6 hours.
Example:
The Earth's orbit around the Sun is nearly circular when viewed from the top.
