That the Moon orbits Earth is one of the first and most basic facts most people learn about physics and astronomy. And it’s certainly intuitive enough: Earth’s only natural satellite moves across our sky each night. But, as this short from the YouTube series MinutePhysics details, if you use the Sun as your frame of reference, the truth becomes much more complicated. Explained via a series of nifty whiteboard-style animations, the video uses the Moon’s trajectory through the cosmos to explore broader, perhaps counterintuitive truths about orbital mechanics.
