Planetary Orbits

 









These are the orbital periods 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 the Sun, Neptune takes nearly 165 years.
