5 de mar. de 2020 · A Kirkwood is a gap or dip in the distribution of the semi-major axes or the orbital periods of the main-belt asteroids. They correspond to the locations of orbital resonances with Jupiter. Key Facts & Summary. Asteroids are not distributed uniformly, and thus some regions contain very few of them. These regions are called Kirkwood gaps.
Kirkwood gaps, interruptions that appear in the distribution of asteroid semimajor axes where the orbital period of any small body present would be a simple fraction of that of Jupiter. Several zones of low density in the minor-planet population were noticed about 1860 by Daniel Kirkwood, an

Key Kirkwood gaps occur at the 2:1, 3:1, 5:2, and 7:3 orbital resonances, while major concentrations of asteroids are found at the 3:2 and 1:1 (Trojan asteroids) orbital resonances. Study Astronomy Online at Swinburne University
The Kirkwood gaps are visible in the main belt. A Kirkwood gap is a gap or dip in the distribution of the semi-major axes (or equivalently of the orbital periods) of the orbits of main-belt asteroids. They correspond to the locations of orbital resonances with Jupiter.
These gaps (labeled "3:1", "5:2", "7:3", "2:1") are caused by mean-motion resonances between an asteroid and Jupiter. For example, the 3:1 Kirkwood gap is located where the ratio of an asteroid's orbital period to that of Jupiter is 3/1 (the asteroid completes 3 orbits for every 1 orbit of Jupiter).
