By speed · Order from slowest to fastest.

1. The creep of a mountain glacier 175320 mm/year

   Glaciers flow downhill under their own weight like very slow rivers of ice, grinding valleys as they go.

2. A record fastball pitch 169 km/h

   A 100-mile-an-hour pitch reaches home plate in under four-tenths of a second, faster than a blink of choice.

3. A golden eagle in a dive 245 km/h

   A golden eagle can spot a rabbit from over three kilometres away, then fold its wings into a lethal stoop.

4. A helicopter at top speed 290 km/h

   A helicopter's top speed is capped because the blade tips would approach the sound barrier and lose lift.

5. A Bugatti Chiron at top speed 510 km/h

   The Chiron is electronically limited; unleashed, its tyres would tear themselves apart from the sheer forces.

6. The International Space Station in orbit 28K km/h

   The station circles Earth so fast its crew sees about 16 sunrises and sunsets every single day.
