Resonance plays an incredibly large role in orbital mechanics [1]. All of the orbits of the moons of Jovian planets are in small fraction ratios of one another.
We are just trained as children to see the small things independently orbiting the big thing, but in reality all bodies orbit each other.
What would this animation look like with one of the moons at the center with Jupiter in a fixed position?
These simplifications are often conceptually not that much simpler, they just have much simpler math. But saying "x is what's happening, but in these circumstances we can treat it as y" is an important skill in science and life, we should teach it more (and benefit from fewer misunderstandings caused by teaching only the simplification)
Nothing orbits anything: everything moves in a straight line; space is curved
