Detailed explanation-1: -Mars is the last planet of the inner four terrestrial planets in the solar system at an average distance of 141 million miles from our Sun. It revolves around the Sun every 687 days and rotates every 24.6 hours (nearly the same as Earth).

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. That longer year means longer seasons too.

Detailed explanation-3: -Earth takes 24 hours to complete one spin, and Mars takes 25 hours. The gas giants rotate really fast. Jupiter takes just 10 hours to complete one rotation. Saturn takes 11 hours, Uranus takes 17 hours, and Neptune takes 16 hours.

Detailed explanation-4: -As Mars orbits the Sun, it completes one rotation every 24.6 hours, which is very similar to one day on Earth (23.9 hours). Martian days are called sols – short for “solar day.” A year on Mars lasts 669.6 sols, which is the same as 687 Earth days.

Detailed explanation-5: -Earth revolves in orbit around the sun in 365 days, 6 hours, 9 minutes with reference to the stars, at a speed ranging from 29.29 to 30.29 km/s.
