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.
Jupiter takes about 11.86 Earth years to complete one orbit around the Sun. This is known as its orbital period or revolution.
It takes the Moon about 27.3 days to complete one full revolution around the Earth. This period is known as its sidereal month.
Neptune takes the longest as it is the farthest away.
Saturn has a period of revolution that is approximately twice as long as Earth's. While Earth takes about 365 days to complete one revolution around the Sun, Saturn takes roughly 29.5 Earth years to complete its orbit.
To find the number of revolution days of a planet, you can use the formula: revolution days = orbital period / rotation period. The orbital period is how long it takes for the planet to complete one orbit around the sun, while the rotation period is how long it takes for the planet to rotate on its axis. This formula will give you the number of days it takes for the planet to complete one full rotation around its axis.
Jupiter takes about 11.86 Earth years to complete one orbit around the Sun. This is known as its orbital period or revolution.
The period of a planet's revolution is the time that it takes to complete one revolution around its axis of rotation relative to the background stars (also known as rotation period).
A revolution is the period it takes for the planet to revolve one time around the sun. Its otherwise known as the planet's year.
Period of rotation
It takes the Moon about 27.3 days to complete one full revolution around the Earth. This period is known as its sidereal month.
The Moon's revolution period around the Earth is approximately 27.3 days. This period is known as the sidereal month, and it is the time it takes for the Moon to complete one orbit around the Earth with respect to the fixed stars.
The Earth completes one revolution around the Sun ina year.(The orbital period of a planet is known as its year, and each planet requires a different period of time to complete a revolution around the Sun. Some take many Earth years.)
Neptune takes the longest as it is the farthest away.
Mercury has the shortest period of revolution around the sun among the planets in our solar system. It takes about 88 Earth days for Mercury to complete one orbit around the sun.
Venus's period of revolution is 225 days.
The earth makes one complete revolution around the sun every 365 and 1/4 days equalling one year.
Saturn has a period of revolution that is approximately twice as long as Earth's. While Earth takes about 365 days to complete one revolution around the Sun, Saturn takes roughly 29.5 Earth years to complete its orbit.
