Question

3. Exact time taken by the earth to complete one revolution
​

Answer 1

The Earth takes 365 days and five hours to make one complete revolution around the sun. The plane that the Earth is in as it orbits the Sun is known as the ecliptic. The orbit of the Earth around the Sun is not a perfect circle.

Answer 2

Answer:

Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes, and 4 seconds with respect to other, distant, stars (see below). Earth's rotation is slowing slightly with time; thus, a day was shorter in the past.
