Neptune is the gas giant furthest from the Sun and Kepler's third law tells us that the period of revolution of a planet around the sun increases as distance from the Sun increases. It does not matter if the planet is a gas giant or not. The law says period depends on distance and not mass.
It takes 60,190 days for Neptune to orbit the Sun which is about
165 Earth years. For that matter, one Neptune Year is 89,666 Neptune days.
If Pluto was still a planet, it would get the record for the longest year since it is, on the average, further than the other planets.
Pluto has an orbital period of 248 earth years. Since Pluto was discovered in 1930, it has only completed about 1/3 of a revolution.
Neptune
Mars takes the longest of the inner planets.
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.
Venus takes the second longest time to orbit the sun, with an orbital period of about 225 Earth days.
which planet takes the longest time to revolve around the sun
Neptune takes the longest to revolve around the sun.
Mars takes the longest of the inner planets.
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.
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.
Neptune takes the longest
When don't they? If a planet is in orbit around a star, it is in continual orbit. Orbital periods (the lengths of time it takes different planets to complete one orbit) are different from planet to planet, and are related to the distances between the planets and their stars.

A planet's year is the time it takes to complete an orbit around the sun. So the planets with the longest years are the ones farthest from the sun. Pluto has the longest in our solar system, followed by Neptune, then Uranus, Saturn, Jupiter, and so on.
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!
As it's the furthest planet out, Neptune takes the longest to orbit our sun, taking some 165 years to do so.
All 8 planets, including dwarf planet Pluto, orbit the Sun. As their distance from the Sun increases, the time it takes for the planet to complete one revolution around the Sun increases as well.

The path a planet takes is called an orbit.The planets are kept in orbit by the gravitational pull of the star (in our case the Sun) they orbit.
The time it takes for a planet to orbit the sun is known as its orbital period. The order of planets from shortest to longest orbital period is: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury has the shortest orbital period of about 88 Earth days, while Neptune has the longest orbital period of about 165 Earth years.
