Earth’s average orbital speed is a mind-blowing 108,000 kilometers per hour — fast enough to travel one earth-diameter in just seven minutes or so. At that speed, surviving on this ball of rock for 46 years, as of today, means that I have traveled roughly 43 billion kilometers in my lifetime, just due to earth’s motion around the sun. Also, by the way, NO, I will not convert this speed, nor this distance, into those annoying non-metric units!
