Simplifying by assuming a circular orbit : Mercury travels 58 million kilometers (Mercury's average distance from the Sun) times 2 "pi", in 88 Earth days. In fact, the answer is about 47.9 kilometers per second, on average. Mercury has a markedly elliptical orbit, which means its speed varies quite a lot during its orbit.
If you mean within our Solar System: Mercury, since it is closest to the Sun.
Mercury is the closest known planet to the sun, in terms of its average orbital distance. It's also the one with the highest speed in its orbit, and the one with the shortest period of revolution or 'year'.Mercury's average distance from the sun: 36 million miles (58 million km)Average orbital speed: 29.7 miles (47.9 km) per secondPeriod of revolution around the sun: 88 earth days
Mercury. Name literally refers to the Messenger of the Gods - and he'd better be fast. Mercury orbits at an average speed of 108,000 miles per hour.

The orbital speeds are higher when closer to the sun, but slower and more similar as you move out. The two that are closest in speed are Uranus and Neptune. Uranus at 6.8352 km/sec and Neptune at 5.4778 km/sec.

Mercury
Mercury is the planet in our solar system that orbits the sun at an average speed of about 170,500 kilometers per hour (at its fastest point).
Of what? orbit: Mercury spin: Jupiter wind: Neptune
Mercury moves the fastest among those planets, with an average orbital speed of about 47.87 km/s. Jupiter, Mars, and Saturn have slower average orbital speeds of about 13.07 km/s, 24.07 km/s, and 9.69 km/s, respectively.
Mercury's orbit around the sun is actually more eccentric than the orbit of any other planet. Mercury's distance from the sun varies between 28 and 44 million miles, and that means that its speed in orbit also varies by a lot. But the average speed over an entire orbit is roughly 29.8 miles per second.
