The path that planets take around the sun is called it's orbit. The gravitation pull of the sun keeps each planet in it's orbit. Each planets orbit varies in the time it takes to make one trip around the sun.
Mercury is the planet closest to the sun.
The outer planets are usually defined as Jupiter, Saturn, Uranus and Neptune. The innermost of those, Jupiter, moves around the sun the fastest. The speed of planet is a function the size of its orbit only -- mass doesn't matter, as figured out by Kepler about 500 years ago. Thus Mercury, the innermost of all planets, has the greatest orbital speed (87.96 Earth days for an orbit), and Neptune the slowest (164.81 Earth years). If you want to include Pluto, then it has the greatest orbital period (247.7 earth years)
If you mean faster than the Earth, then the planets Mercury and Venus orbit faster. This is because they are closer to the sun.
Curiously, the nearer the planet is to the Sun the faster it orbits. Thus Mercury orbits the fastest, whereas Neptune is the slowest.
The earth is moving fastest in its orbit at the moment of perihelion, when it is closest to the sun. the happens around January 3.
The speed of a planet is fastest when it is closest to the sun in its orbit (option 1) and slowest when it is farthest from the sun (option 2). This is because of the gravitational pull of the sun, which accelerates the planet as it gets closer and decelerates it as it moves away.
The fastest planet is Mercury which is closest to the Sun.

Mercury moves the fastest 48 km/s
A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.

Mercury is the closest planet to the sun. Because of this, it revolves around the sun the fastest.
