Retrograde Motion and the Copernican Explanation
The modern explanation for retrograde motion is just that, in a heliocentric (Sun-centered) model, the inner planets orbit the Sun faster than the outer planets, so that (for example) when the Earth overtakes Mars then there is an apparent backwards motion relative to the background as we pass. Here, you can follow the arrow sight line to see ...

We created this animation to visualize the captivating retrograde motion of Saturn — a cosmic illusion that has puzzled skywatchers for millennia. In 2025, Saturn begins its retrograde on July 13 and continues this apparent backward journey through the stars until November 15. But what exactly is retrograde motion? It’s not that Saturn actually reverses its orbit — instead, it’s an optical illusion that occurs when Earth, on its faster inner orbit, overtakes the slower-moving Saturn. As we pass
