Jupiter’s Influence on the Asteroid Belt

Jupiter’s Gravitational Influence on the Asteroid Belt

What You’re Seeing:

This simulation demonstrates how Jupiter (the larger circle) affects asteroids in the belt (small dots).

Main observable phenomena:

  • Orbital alterations: Notice how asteroid orbits change in eccentricity and inclination over time due to Jupiter’s gravitational influence.
  • Orbital resonances: Observe how asteroids at certain distances are more affected than others, demonstrating resonance zones.
  • Ejection: Some asteroids will be ejected from the belt, either toward the inner Solar System or out to space.

Interactivity:

  • Use the slider to change Jupiter’s mass and observe how this affects the intensity of gravitational effects.
  • Toggle Jupiter’s presence to compare the belt’s behavior with and without its influence.
  • Adjust the simulation speed to observe effects at different time scales.

Kepler’s Laws of Planetary Motion

Kepler’s Laws Demonstrated:

  1. First Law (Law of Elliptical Orbits): Planets move in elliptical orbits with the Sun at one focus.
  2. Second Law (Law of Equal Areas): A line connecting a planet to the Sun sweeps out equal areas in equal times.
  3. Third Law (Law of Harmonies): The square of a planet’s orbital period is proportional to the cube of its semi-major axis.

Adjust the eccentricity slider to change the shape of the orbit. A value of 0 creates a circular orbit, while higher values create more elliptical orbits.
