    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 .

  2. From Simple English Wikipedia, the free encyclopedia Kirkwood gaps 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 .

  3. 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). The effect of these mean-motion resonances is a change in the asteroid's orbital elements (particularly semimajor axis) sufficient to create these gaps in semimajor axis space.

  4. 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). The effect of these mean-motion resonances is a change in the asteroid's orbital elements (particularly semimajor axis) sufficient to create these gaps in semimajor axis space.

    • English: This histogram clearly shows the primary Kirkwood gaps in the asteroid main-belt. 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). The effect of these mean-motion resonances is a change in the asteroid's orbital elements (particularly semimajor axis) sufficient to create these gaps in semimajor axis space., Español: Este histograma muestra claramente los huecos de Kirkwood primarios del cinturón principal de asteroides. Estos huecos (marcados "3:1", "5:2", "7:3", "2:1") se originan por las resonancias orbitales entre un asteroide y Júpiter. Por ejemplo, el hueco de Kirkwood 3:1 se localiza en el punto en el que el periodo orbital del asteroide guardaría una relación de 3/1 con el de Júpiter (el asteroide completaría justo tres órbitas por cada una de Júpiter). El efecto de estas resonancias orbitales son cambios en los elementos orbitales de los asteroides (principalmente en su semieje mayor) suficientes para generar estos huecos en la distribución espacial de las órbitas asteroidales.

  5. 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. Histogram showing the four most prominent Kirkwood gaps and a possible division into inner, middle and outer main-belt ...

  6. Original definition implied that gaps were in a distribution along some undefined axis of the universe of "all asteroids having a semi-major axis" as opposed to asteroids without one. All asteroids do have a semi-major axis.
