Neptune takes the longest as it is the farthest away.
Mercury has the longest year in revolution among the inner planets, taking about 88 Earth days to complete one orbit around the Sun.
Neptune.
If you still consider Pluto to be a planet, then the answer is Pluto, which completes one revolution around the sun in 248 years. If you agree with the downgrading of Pluto to something less than a full-fledged planet, then the answer is Neptune. The general rule is: The farther a planet is from the sun on the average, the longer it takes to complete its orbital revolution.
Technically, since Pluto is no longer a planet, but a dwarf planet, Uranus is the planet that takes the longest to orbit the sun.
Around its axis is a day. Around its orbit is a year.
Mercury has the longest year in revolution among the inner planets, taking about 88 Earth days to complete one orbit around the Sun.
Neptune has the longest period of revolution among all planets in our solar system, taking about 165 Earth years to complete one orbit around the Sun.

A revolution is the period it takes for the planet to revolve one time around the sun. Its otherwise known as the planet's year.
One complete revolution of a planet around the sun equals one year.

Mercury is the shortest and Neptune is the longest
One complete orbit of a planet around the sun is called a revolution.
