One round trip around the sun is called a "YEAR".
Depends on whether or not you call Pluto a Planet. If so, yes Pluto. Which takes around 248 earth days to orbit the sun. If not, it's Neptune. Which takes 165 earth days to orbit the sun.
That is called the planet's orbit.
A planet that orbits a star is called an exoplanet.
I believe you are asking about their orbits around the Sun. The orbit is the (elliptical) path they take around the Sun. It takes a certain amount of time to complete, which is the planet's "year".One calendar year on Earth is (more or less) the time for one full revolution of Earth around the Sun.
U answer
revolution
We call that path the "orbit" of the orbiting body. Note: You would not ever see a planet orbiting another planet. At least, if you did, you would not call them both planets.
The path a planet takes is called an orbit.The planets are kept in orbit by the gravitational pull of the star (in our case the Sun) they orbit.
An orbit.

The journey a planet makes around the sun is called its orbit.
