How many miles does the earth cover in orbit around the sun?
The surface speed of the Earth’s rotation at the equator is 465.11 m/s, while the average orbital speed is 29783 m/s, a good 6 times faster. The orbital circumference would be 2AU*pi, where AU is the astronomical unit, the distance from the Earth to the Sun, or 149597870691 m. So the circumference is 2*149597870691*pi = 939951143084 m, or 584058562 miles, which is very close to your answer; you probably just rounded differently or used a different value for AU.
