Speed Comparison: From Walking to the Fastest Spacecraft
From a walk at 5 km/h to the fastest object ever built: 13 racers in one continuous race, all moving at their real speeds. Usain Bolt, a car, a bullet train, an airliner, Concorde, the SR-71, the X-15, the ISS, Apollo 10, Voyager 1, Helios 2 and NASA’s Parker Solar Probe each overtake the one before. There’s no slow motion and no speed-up. At 692,000 km/h, Parker is about 138,000 times faster than walking. It could cross from New York to London in 29 seconds.
