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
As it's the furthest planet out, Neptune takes the longest to orbit our sun, taking some 165 years to do so.
Mars takes the longest of the inner planets.
Uranus
Neptune takes the longest
Approxiamtely 6756313285.666678487m
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.
Neptune.
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.
Planets have years based on the time it takes them to orbit the sun. The sun does not orbit itself, so it does not have a year.Planets have years based on the time it takes them to orbit the sun.

Neptune is the furthest planet from the sun, taking the longest time to complete one orbit, 164.79 years in total.
AnswerNeptune has the farthest average distance from the Sun of the 8 major planets. Not only is its orbit vastly longer, but it also moves more slowly in that orbit, because the reduced gravitational attraction of the Sun requires it to have comparatively less orbital momentum to counteract it. Neptune takes about 164.8 Earth years to make one orbit of the Sun.
Jupiter takes 11.86 Earth years to orbit the Sun - this is the 4th longest orbital period.
