the worlds highest average wind speed is 231 mph
Earth has the highest mean density of any planet in the solar system.
Venus has the highest average surface temperature, which is equal to 464C.
The highest speed is 115 mph (71.5 metres per second).
According to Kepler's Third Law, the planets that are nearer to the Sun movefaster than the planets that are farther away. The closest planet - and thus thefastest - is Mercury; the farthest planet from the Sun is Neptune.==================================The way gravity works guarantees, that the closer an object is to the sun, the faster it moves, whether the orbit is almost circular or highly eccentric. This simplerule instantly lines up the speeds of the various solar system objects for us:Fastest speed:Comets which, at their closest approach, spend part of their time inside the orbit of Mercury.Their speed is highest when they're closest to the sun.Known planet with the highest average speed:The planet nearest the sun . . . Mercury.Known planet with the lowest average speed:The planet farthest from the sun . . . Neptune.Known dwarf-planet-like objects with the lowest average speed:Known objects farthest from the sun . . . Pluto, Eris.
The closest one goes the quickest - Mercury.
I'm not to sure on the average wind speed but i know the highest wind speed recorded is 200mph hope this helped
