The cheetah has long been known as the world’s fastest land animal, but few understand just how incredible the cat must be to hold such an impressive title.

The average cheetah can accelerate to 75 MPH in just three seconds, the time it takes for just three strides. Every part of the cheetah is built for speed, from its light weight body to its flat head.

The big cat runs so fast, its legs spend more time in the air than on the ground.

Now, this video by Smithsonian Channel from last October is going viral only now since the weekend.
