By speed · Order from slowest to fastest.

1. A foraging ant 800 m/h

   Ants leave scent trails so nestmates can retrace the exact path to food, like an invisible chemical map.

2. A person jogging 10.8 km/h

   Humans are among the best endurance runners on Earth, able to outlast horses over very long distances in heat.

3. A common swift in flight 113 km/h

   Swifts can stay airborne for nearly a year without landing, even sleeping on the wing high above the ground.

4. An ice hockey slapshot 178 km/h

   A slapshot flexes the stick like a spring, snapping stored energy into the puck for a brutal release.

5. The core of a jet stream 442 km/h

   Pilots ride these high-altitude winds to save fuel, which is why eastbound flights are often much quicker.

6. A meteor entering the atmosphere 50K km/h

   Most shooting stars are no bigger than a grain of sand, burning up bright from sheer speed alone.
