One year on a planet refers to the time it takes for it to complete a single orbit around the sun. Due to the vast differences in the sizes of the planets in our solar system and their distances from the sun, the lengths of their years can vary significantly.

The planet with the longest year in our solar system is Neptune, the eighth planet from the sun. It takes approximately 164.8 Earth years for Neptune to complete one orbit around the sun.

Compared to Neptune, the planet with the shortest year in our solar system is Mercury, the closest planet to the sun. It takes just 88 Earth days for Mercury to complete one orbit around the sun.
