Explanation:
Detailed explanation-1: -Earth is closer to the sun and revolves around it in about 365 days. Sentences: Earth revolves around the sun in 365 days, 5 hours, 59 minutes and 16 seconds. The time a planet takes to revolve around the sun is called a year.
Detailed explanation-2: -The time period (T) of revolution of the planet depends upon the radius of the orbit (r), mass of the sun (M) and the gravitational constant (G).
Detailed explanation-3: -The law of periods: The square of the period of revolution (T) of any planet around the sun is directly proportional to the cube of the semi-major axis of the orbit i.e. T2 ∝ r3.
