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.
