Mars takes the longest of the inner planets.
Uranus
IN our solar system, the planet Neptune takes the longest. Or, if you want to include Pluto, Pluto. Or, if you want to include ALL of the "dwarf planets", then Eris (a.k.a. "Xena") takes the longest.
which planet takes the longest time to revolve around the sun
Pluto has the longest year, if it was still a planet that is, equal to 248.76 Earth years. Since Pluto is no longer considered a planet, the planet with the longest year is Neptune, at 164.8 Earth years per revolution around the Sun.
Mars takes around 687 days to make one orbit of our sun.
As it's the furthest planet out, Neptune takes the longest to orbit our sun, taking some 165 years to do so.

Technically, since Pluto is no longer a planet, but a dwarf planet, Uranus is the planet that takes the longest to orbit the sun.
Neptune with an orbit time of 165 years.(note:even though Pluto takes 248 years to orbit the sun it is classified as a asteroid not a planet)-Mihi
Neptune is the furthest planet from the sun, taking the longest time to complete one orbit, 164.79 years in total.
Jupiter takes 11.86 Earth years to orbit the Sun - this is the 4th longest orbital period.
Depends on whether or not you call Pluto a Planet. If so, yes Pluto. Which takes around 248 earth days to orbit the sun. If not, it's Neptune. Which takes 165 earth days to orbit the sun.
As Pluto is no longer considered a planet, the planet with the longest orbital period is Neptune. The Neptunian year is approximately 60,190 Earth days.
A year (or orbital period) is defined as the period it takes a planet to orbit the Sun.
As planets are found in orbits further out from the Sun, these will take longer to complete an orbit - basically they have further to travel to complete an orbit. However to stay in orbit they do not have to travel as fast (to stay in orbit) as planets closer to the Sun. This is because the force of gravity falls of with the square of the distance the two bodies are apart. The Suns outermost planet is Neptune (Pluto is no longer a planet) and it takes 164 Earth years to orbit the Sun!
