The close-in ones move fast, the far-out ones move slower. It's governed by Kepler's third law.
They move faster.
Closest to the sun
Mars takes longer to make one orbit of the sun. Its slower, and it also has further to go. Planets orbiting speeds get slower the further you go out.
Planets orbit the sun at different speeds because they are at varying distances from the sun. According to Kepler's laws of planetary motion, planets closer to the sun have faster orbital speeds, while those farther away have slower speeds. This is due to the gravitational force exerted by the sun, which is stronger on planets closer to it.

Pluto's orbit is longer and slower than other planets.
The closer planets are to the Sun the faster their orbit speed
They move faster.
Closest to the sun
Yes.
Kepler found that all planets move in elliptical orbits, with the sun being at one focus. Kepler also announced that the speed an object traveled along it's path varied according to how close the object was to the sun. He also announced that the larger a planet's orbit, the slower it travels.

Slower or faster than what? - When the Earth is nearer the Sun (periapsis), it moves faster than when it is farther away from the Sun (apapsis).
Well, the speed of it's orbit in relation to the other planets orbiting the same sun. The closer an object is to the sun the faster it's orbit. Conversely, the farther an object is from the sun the slower it's orbit.
the fastest planet that orbit's the sun is mercury.
Since the gravitational effect of the Sun decreases with distance from it, the planets farther from the Sun do not have to move as rapidly to remain in orbit. (In fact, the speed is what establishes the orbit, not the other way around.) So the outer planets, in addition to having much farther to travel in their orbits, are also moving more slowly. This combination means that outer planets take very much longer to orbit the Sun than do the inner planets such as Earth. By comparison, the length of time it takes (in Earth years) for each of the outer planets to make one complete revolution around the Sun: Jupiter - 11.9 Earth years Saturn - 29.5 Earth years Uranus - 84 Earth years Neptune - 165 Earth years
