Detailed explanation-1: -The time it takes for an object to orbit around another object is called its orbital period. Earth completes its orbital period around the sun every 365 days. The further away a planet is from the sun, the longer its orbital period.
Detailed explanation-2: -The second law (Law of areas): The radius vector drawn from the sun to the planet sweeps out equal areas in equal intervals of time.
Detailed explanation-3: -Kepler’s third law-sometimes referred to as the law of harmonies-compares the orbital period and radius of orbit of a planet to those of other planets.
Detailed explanation-4: -One complete orbit takes 365.249 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi).
