Location of the main belt This plot shows the location of the main belt with respect to the planets and the Sun as well as the orbital structure of asteroid inclinations and number density of objects (yellow represents the highest number density, blue the lowest). Figure from DeMeo and Carry (2014).
The Simple English Wiktionary has a definition for: asteroid belt. The asteroid belt or main belt is a ring of small and large rocks and dust between the orbits of Mars and Jupiter. The biggest object in the asteroid belt is Ceres, a dwarf planet. The Kirkwood gaps separate the asteroid belt into several groups.
Jan 1, 2014 · Once its eccentricity reaches a value of about 0.3, a main-belt asteroid's orbit begins to approach or even cross the orbit of Mars. Close encounters with Mars can further alter its orbit, leading to interactions with the other inner planets or with Jupiter, which eventually results in a collision with either a planet or the Sun, or ejection ...

Category. : Main-belt asteroids. Wikimedia Commons has media related to Main Belt asteroids. If possible, asteroids should always be placed into one of the numerous sub-categories, in line with the category information given in the minor-planet catalog. Used sources: Small Body Data Ferret (Nesvorný) and AstDys (Milani and Knežević).
A minor-planet moon is an astronomical object that orbits a minor planet as its natural satellite. As of January 2022, there are 457 minor planets known or suspected to have moons. [1] Discoveries of minor-planet moons (and binary objects, in general) are important because the determination of their orbits provides estimates on the mass and ...
Jan 18, 2008 · The main belt region is shown in red, and contains 93.4% of all the objects. For reference, Mars orbits out to 1.666 AU, and Jupiter between 4.95 and 5.46 AU. The diagram was created by Piotr Deuar using orbit data for 120437 numbered minor planets from the Minor Planet Center orbit database, dated 8 Feb 2006.
Other articles where main-belt asteroid is discussed: asteroid: Distribution and Kirkwood gaps: …AU, a region called the main belt. The mean distances are not uniformly distributed but exhibit population depletions, or “gaps.” Those so-called Kirkwood gaps are due to mean-motion resonances with Jupiter’s orbital period. An asteroid with a mean distance from the Sun of 2.50 AU, for ...
