Detailed explanation-1: -Mercury is the smallest planet in the Solar System and the closest to the Sun. Its orbit around the Sun takes 87.97 Earth days, the shortest of all the Sun’s planets.

Detailed explanation-2: -Fastest Planet The closer a planet is to the Sun, the faster it travels. Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system – 88 days.

Detailed explanation-3: -At an average distance of 36 million miles, Mercury is the closest planet to our Sun. It revolves around the Sun every 88 days, but its rotation takes nearly 59 days. Therefore Mercury completes three rotations for every two orbits around the Sun.

Detailed explanation-4: -Planets that orbit closer to the Sun than Earth have shorter years than Earth. Planets that orbit farther from the Sun than Earth have longer years than Earth. This happens for two main reasons. If a planet is close to the Sun, the distance it orbits around the Sun is fairly short.

Detailed explanation-5: -A single year lasts only 88 days on Mercury, but thanks again to its slow rotation, a day lasts twice as long! That means that if you could stand on the surface of Mercury, it would take a staggering 176 Earth days for the Sun to rise, set and rise again to the same place in the sky just once!
