There is no planet that revolves around the Sun with a period of 288 years.
Neptune is the furthest planet from the sun, taking the longest time to complete one orbit, 164.79 years in total.
On Earth, a year is the time Earth takes to travel once around the Sun. The term "year", applied to other planets, may either refer to a standard Earth year, which is a very convenient unit of time, or to the time the planet takes to go once around the Sun. As an example, a "year" on Jupiter takes about 12 Earth years.
Mercury
It takes Saturn 29.45 years (or 10759 days) to orbit, or revolve around, the Sun once. It takes about 29.5 Earth years for the planet Saturn to revolve once around the sun. 10,579 earth days
the time it takes to travel around the sun, a planet year
If you still consider Pluto a planet, than Pluto takes the longest time to move around the sun. If not, Neptune takes the longest amount of time.
The dwarf planet Pluto. No "planet" takes that time.
The one that is the biggest distance away, that's Neptune 164 years, but dwarf planet Eris takes 550 years.
84.02 Earth years
It takes about 84 Earth years.
Saturn
The planet with the nearest orbital time is Uranus. That takes about 84 Earth years.
Neptune is the furthest planet from the sun, taking the longest time to complete one orbit, 164.79 years in total.
It differs from planet to planet
which planet takes the longest time to revolve around the sun
Our planet takes 24 hours (one day)
The orbital speed of a planet is the time it takes to cycle around the sun. The spinning speed of a planet is the time it takes for the planet to rotate on it's axis.
