Kirkwood gap

gap or dip in the distribution of the semi-major axes of the orbits of main-belt asteroids

Kirkwood gaps are areas of the asteroid belt where asteroids are unusually scarce, as seen in the graph on the right. They are caused by orbital resonances with Jupiter.

Kirkwood gaps

The gaps were first noticed in 1857 by Daniel Kirkwood, who also correctly explained their origin in the orbital resonances with Jupiter while a professor at Jefferson College in Canonsburg, Pennsylvania.[1]
