Explanation:
Detailed explanation-1: -As we all know Neptune is the farthest planet from the sun. Hence, Neptune will have a maximum radius of orbit. While mass and gravitational constant are the same for all the planets. Hence, we conclude that Neptune will take maximum time to complete one revolution around the sun.
Detailed explanation-2: -The Earth zips around the Sun at about 67, 000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year.
