By speed · Order from slowest to fastest.

1. A charging African elephant 28 km/h

   Despite their bulk, elephants are the only animals that cannot jump, keeping at least one foot down at all times.

2. A bottlenose dolphin 60 km/h

   Dolphins sleep with half their brain at a time, keeping one eye open to breathe and watch for danger.

3. 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.

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 maglev train at record speed 460 km/h

   Maglev trains float on magnets with no wheels, so the only friction left to overcome is the air itself.

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.
