By speed · Order from slowest to fastest.

1. A person walking 5 km/h

   The average person takes around 7,000 steps a day, walking the equivalent of several times around Earth in a lifetime.

2. A running pronghorn antelope 97 km/h

   The pronghorn can run far faster than any predator alive today, likely escaping a cheetah that went extinct in America.

3. A golf ball off the driver 340 km/h

   A driven golf ball can briefly spin thousands of times a minute, which is what makes it climb and hold the air.

4. An F-22 Raptor at top speed 2.4K km/h

   The Raptor can supercruise, flying faster than sound without afterburners, sipping less fuel as it streaks along.

5. The SR-71 Blackbird 3.5K km/h

   The Blackbird leaked fuel on the ground because its panels only sealed once heat expanded them in flight.

6. The Earth orbiting the Sun 107K km/h

   We are all hurtling around the Sun fast enough to cross between two cities in a single second, yet we feel nothing.
