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 wild boar running 45 km/h

   Wild boars are spreading across the globe, rooting up so much soil they reshape entire ecosystems.

3. 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.

4. 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.

5. A Boeing 747 cruising 920 km/h

   The 747's hump exists because the cockpit was put on an upper deck so the nose could hinge open for cargo.

6. NASA's Parker Solar Probe 692K km/h

   The fastest human-made object ever, it slingshots around the Sun, dipping into the star's blazing outer atmosphere.
