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!

Neptune is nor the furthest from the Sun. It takes about 165 years to orbit the Sun because it has such an incredible distance to travel.Pluto has been removed from the list of planets.

When Pluto was considered a planet it claimed that title, but now Neptune has the longest orbit because it is farthest away from the Sun, thus making it have a longer orbit.

Why does Neptune take the farthest to revolve around the sun?

Neptune takes the longest because it is the 8th planet so it takes longer to get to the sun and because it is so big


What planet has the slowest rotation rate?

The velocity of a planet around the sun is inversely related to the distance from the sun. So the slowest planets are the ones farthest out. If you consider Pluto a planet, it takes the longest time to revolve around the sun. If you do not consider Pluto a planet, then Neptune would be the farthest planet from the sun and takes the longest time to revolve around the sun.


How does your planet's distance from the sun affect how long it takes to revolve around the sun?

Because the farther away a planet is from the sun the bigger its orbit is and that will make a revolution longer.example: Neptune is the farthest planet from the sun and it takes 164 earth years to revolve around the sun and Mercury is the closest planet from the sun and it takes 88 earth days to revolve around the sun.
