Mercury, Venus to Mars, know how long it takes all planets to orbit the Sun
December 31 is celebrated as New Year every year to mark the completion of Earth's orbit around the Sun. It takes roughly 365 days for the Earth to complete revolution around the Sun. The closer a planet is to the Sun, the stronger its gravitational pull and the faster it moves.
Do the other planets take the same number of days as the Earth to complete the trip around the Sun? The answer is no.
So, learn how many days it takes each planet to complete one revolution of the Sun. The planets in our solar system are divided into 2 parts, depending on their proximity to the Sun. They are divided into Inner Solar System and Outer Solar System.
Inner Solar System
The Inner Solar System consists of planets Mercury, Venus, Earth and Mars. Mars being closest to the Sun takes the shortest trip around the Sun, so it takes the least number of days. Mercury completes one revolution around the Sun in just 88 days. Venus is the 2nd closest planet to the Sun and therefore is the 2nd fastest. So, it completes one trip around the Sun in 225 days. Earth is 3rd closest planet to the Sun. Earth takes roughly 365 days to complete one year. Mars is the outermost planet of the Inner Solar System. The red planet takes 687 days to complete one trip around the Sun.
Outer Solar System
The Outer Solar System consists of planets Jupiter, Saturn, Uranus and Neptune. The planets in the Outer Solar System take considerably longer to complete one trip around the Sun. Jupiter, also called the Gas Giant, takes 4,333 days to complete one trip around the Sun. To put that into context, one year on Jupiter is almost 12 years on Earth! Saturn takes 10,759 to complete one trip around the Sun. Uranus takes 30,687 days to complete one revolution. However, Neptune will amaze you! Neptune takes 60,190 days to complete one trip around the Sun. Since being discovered in 1846, Neptune has only completed one trip around the Sun.
