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.
Starry Greetings!

“ ...The lingering airglow is due to chemiluminescence, the production of light through chemical excitation. Originating at an altitude similar to aurora, it can found around the globe. The chemical energy is initially provided by the Sun's extreme ultraviolet radiation.” X
