Neptune
Neptune takes 164.79 Earth years to orbit the sun once.
Neptune's orbit takes 125 years to get around 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!
Planet Neptune takes the most time to orbit the sun, as it is the farthest away.
Neptune has a longer year than Mercury. The closer to the sun a planet is, the faster the orbit and shorter the year. Neptune's orbital period (year) is a little under 165 Earth years. Mercury orbits the sun in just under 88 days.
Neptune.
Neptune. Because it was the farthest planet from the sun. So its orbit's length is long.
Neptune takes 164.79 Earth years to orbit the sun once.
Neptune is the only planet that takes longer than Uranus to orbit the Sun.
Neptune's orbit takes 125 years to get around the sun.
Depends on which planet/sun!Neptune!!

Neptune has the longest orbit of any planet in our solar system, about 18 billion km (11 billion miles). Neptune requires nearly 165 years to complete one solar orbit. Eris take 557 years to journey once around our 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.
Neptune has a longer year than Mercury. The closer to the sun a planet is, the faster the orbit and shorter the year. Neptune's orbital period (year) is a little under 165 Earth years. Mercury orbits the sun in just under 88 days.
