That would be Saturn.
Uranus takes 84 earth years to travel around the sun.
Venus because it is closer to the sun than Earth.
Saturn
An orbit is the path a planet takes around the sun. Earth's orbit is an ellipse. It takes the Earth one year to travel along the elliptical path around the sun.
No, actually it takes 365.26 days to orbit around the sun. This is one year.
The orbital period of Saturn is 29.43 earth years.
It takes Jupiter approximately 12 years to orbit the sun.
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.
No planet goes around the Earth. The Moon, Earth's satellite orbits around the Earth, once ever 27 days and 7 hours.
The closest planet to Earth is Venus. The time it takes to travel to Venus depends on its position in its orbit relative to Earth, but on average, it takes about 3-4 months using current space travel technology.
You're talking about Pluto. But the correct figure is 248 earth-years, not days.
No planet travels around the world. All planets travel around the sun. This is called the solar system.
