Neptune's orbit is close to 164 years.
The outer planets take longer to orbit the Sun, because they are farther away from the Sun. It make its gravitational pull weaker to the farther planets. That means that the outer planets take longer to orbit the Sun.
Yes.They have winter ,summers etc. The seasons of Uranus lasts for 20 years because of its TILT.
Outer planets like Jupiter, Saturn, Uranus, and Neptune take varying amounts of time to orbit around the Sun due to their distance from it. Jupiter takes about 12 years, Saturn about 29 years, Uranus about 84 years, and Neptune about 165 years to complete one orbit.
The inner planets are rocky, with distinct solid surfaces, and dense, whereas the outer planets are gaseous, have no solid surface and are relatively light in comparison. The density of Saturn, for example, is less than that of water.
Jupiters orbit is a imaginary circle that the planets circle around that is how we count years.
Neptune is the furthest planet from the sun, taking the longest time to complete one orbit, 164.79 years in total.
Pluto is more like an inner planet and is very cold, the outer planets are gas. The outer planets are cold Pluto.Aside from being, on average, the farthest planet from the Sun, Pluto and its orbit have several characteristics that make it unique. Its greater distance means its orbital period of 248 years is the longest of all planets. Its orbit has the highest eccentricity, which means that its distance from the Sun varies more than other planets. Its orbit is so far from circular that it can actually be closer to the Sun than Neptune at times.The plane of Pluto's orbit is also tilted the most compared to the rest, taking it further north and south of the Earth's orbital plane than the otherplanets.

Since the gravitational effect of the Sun decreases with distance from it, the planets farther from the Sun do not have to move as rapidly to remain in orbit. (In fact, the speed is what establishes the orbit, not the other way around.) So the outer planets, in addition to having much farther to travel in their orbits, are also moving more slowly. This combination means that outer planets take very much longer to orbit the Sun than do the inner planets such as Earth. By comparison, the length of time it takes (in Earth years) for each of the outer planets to make one complete revolution around the Sun: Jupiter - 11.9 Earth years Saturn - 29.5 Earth years Uranus - 84 Earth years Neptune - 165 Earth years

Pluto's orbit is more elliptical than the major planets' orbits, and every time it goes round it spends some years inside Neptune's orbit.
The reason for the slower movement of outer planets answers to the simple nature of the gravitational force, which varies with the inverse square of distance. For example, an object twice as distant would feel one quarter the gravitational pull. For a stable orbit, this would mean an outer planet would have to move more slowly. Meanwhile, the inner planets move more quickly, and Mercury, with an orbit closest to the sun, zips around it in only 88 days, compared to Naptune's 165 years.
