Mercury\xa0is the fastest planet, which speeds around the sun at 47.87 km/s. In miles per hour this equates to a whopping 107,082 miles per hour. 2. Venus is the second fastest planet with an orbital speed of 35.02 km/s, or 78,337 miles per hour. The orbital\xa0speed\xa0can be found using v = SQRT(G*M/R). The R value (radius of orbit) is the earth\’s radius plus the height above the earth – in this case, 6.77 x 106\xa0m.\xa0This means that\xa0Jupiter\xa0has the shortest days of all the planets in the solar system. Venus is the slowest – it rotates once every 243 days —- by far the slowest rotation period of any of the major planets. A Venusian sidereal day thus lasts more than a Venusian year (243 versus 224.7 Earth days).
