Watch the motion carefully. Repeat Question 1, but place the asteroid at some random spot 2.50 AU from the Sun. For some reason, scrolling the applet out of the window erases it. I know it's annoying, but I haven't figured out how to fix it yet. For now, just try not to scroll while running the simulation.
Resonances can strongly affect the motion of asteroids.
Look at the following graph of mean distance from the Sun versus number of actual asteroids with that mean distance. You should notice several spots where there are almost no asteroids. These gaps are known as the Kirkwood gaps , and they all correspond to resonances with Jupiter. Be sure to note any differences in how the asteroid behaves. Now that you have an idea of what most resonances do, let's examine a few of the anomalous ones.
