Which Planet has the Longest Year?

The correct answer is Neptune.

Neptune has the longest year of all the planets in our solar system. It takes about 164.8 Earth years for Neptune to complete one orbit around the Sun. This long orbit is due to Neptune's considerable distance from the Sun, as it is the eighth planet in our solar system and is located far beyond the orbits of the inner planets like Earth and Mars.
