NPR's Science Tumblr "Skunk Bear" shared these awesome gifs that demonstrate how long it takes each planet in our solar system to travel around the sun.

Here's the orbital period of our solar system's 8 major planets (how long it takes each to travel around the sun). Their size is to scale and their speed is accurate relative to Earth's. The repetition of each GIF is proportional to their orbital period. Mercury takes less than 3 months to zoom around Sol, Neptune takes nearly 165 years.
