Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the laplace resonance?The 1:2:4 resonance between Jupiter's moons Io, Europa, and Ganymede
2. What is the neptune-pluto dynamics?A 2:3 resonance ensures safe orbital separation between Neptune and Pluto
3. Why do Jupiter's moons have a 1:2:4 resonance?The moons Io, Europa, and Ganymede orbit in a 1:2:4 pattern, meaning for every one orbit of Io, Europa does two and Ganymede does four. This pattern keeps their orbits predictable and stable. It shows how gravity can lock moons into a rhythm.
4. How does orbital resonance create gaps in asteroid belts?When asteroids orbit at a rate that matches Jupiter's pull, their paths get nudged each time. Over many orbits, the asteroids move away, leaving empty spots called Kirkwood gaps. These gaps show where resonances happen.

Celestial Mechanics: The branch of astronomy concerned with the motion of celestial bodies under the influence of gravity.
Orbital Perturbation: A deviation in an astronomical object's orbit caused by external gravitational forces.
Commensurable Orbits: Orbits whose periods are in a simple integer ratio, leading to resonance.
