Orbital resonance?

Question

why it may cause to chaos ? - why does it matter

.Thank you!! .ok. so what determine whether the system be stable or chaotic ?

Answer 1

Orbital resonance occurs when two bodies orbiting a third body (moons of a planet, for example) have orbital periods that are integer multiples of the other: moon A orbits 4 times while moon B orbits 5 times, for example. It's important, because the perturbations on the orbit of one by the other will have a position and time regularity that will then cause the orbits to change, possibly driving the system into a chaotic state.

Answer 2

There are stable orbital resonance between planets, moons, or ones that are unstable like Saturn’s inner moons and its rings, giving rise to gaps in the ring system. The definition is defined in celestial mechanics when two orbiting bodies exert a regular periodic gravitational influence on each other.

Stable resonance define certain events such as conjunctions over time and are the result of simple ratios, and they never closely approach. Unstable ones will result in material being ejected. Lesser bodies that cross orbits with for example Neptune are thrown out of the area by perturbations exerted on them by Neptune.

Answer 3

Hi. The best example may be Pluto. It has a period that makes it resonate with Neptune in such a way that it stays in orbit. Chaotic behavior should eject it from its orbit.
