Revolution of a planet can mean two things:

* orbital period - the time it takes to orbit the Sun - then the answer is Neptune, the farthest planet. Neptune takes about 165 years to orbit the sun once. It is thus the planet in our solar system with the longest period of revolution. The dwarf planet Sedna may take as long as 12,000 years to orbit the sun.

* rotational period - the time it takes to spin on the axis - then the answer is Venus. Venus has the longest period of rotation (day) at 243 Earth days.

Eris, which is larger than Pluto, orbits once every 557 years.

The planet with the longest period of revolution is?

Neptune has the longest period of revolution among all planets in our solar system, taking about 165 Earth years to complete one orbit around the Sun.


Which planet takes maximum period to complete 1 revolution around the sun?

If you still consider Pluto to be a planet, then the answer is Pluto, which completes one revolution around the sun in 248 years. If you agree with the downgrading of Pluto to something less than a full-fledged planet, then the answer is Neptune. The general rule is: The farther a planet is from the sun on the average, the longer it takes to complete its orbital revolution.


Which outer planet has the longest day?

Uranus has the longest day of any planet in the solar system, with a rotation period of about 17 hours and 14 minutes.

What planet is short?

The Period of revolution decribes the time taken for an object to orbit another or the orbital period. For the Gas giant planets, this is the closest of the four - Jupiter. the closer a planet is to the sun (or any orbiting object is to another), the shorter the period of revolution. Jupiters period of revolution about the sun is 11 years and 314 days. The rotation period is the time it takes a planet to spin once on its axis, rotating about its axis. This has no relationship to the planet to sun distance, although again it is Jupiter at 9h 55 mins to make one turn. This is the quickest out of all eight planets.


One day on which planet equals 318 earth days?

There are no planets in our solar system with a rotational period of 318 days. The longest is Venus, with a rotational period of 243 days.


How would you define revolution of Planets in the solar system?

The revolution of planets in the solar system refers to the motion of a planet in its orbit around the Sun. Each planet follows an elliptical path with the Sun at one of the foci. The time it takes for a planet to complete one revolution is known as its orbital period.
