The asteroid belt is the smallest and innermost known circumstellar disc in the Solar System. Classes of small Solar System bodies in other regions are the near-Earth objects, the centaurs, the Kuiper belt objects, the scattered disc objects, the sednoids, and the Oort cloud objects. About 60% of the main belt mass is contained in the four ...
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).
Active asteroids are small Solar System bodies that have asteroid -like orbits but show comet -like visual characteristics. [1] That is, they show a coma, tail, or other visual evidence of mass-loss (like a comet), but their orbits remain within Jupiter 's orbit (like an asteroid). [2] [3] These bodies were originally designated main-belt ...
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).
Feb 28, 2019 · This workshop brings together experts to establish the current understanding of Main Belt asteroid science, as well as to debate future directions for investigation. The workshop stimulates discussions about accretion, chemistry, collisions, dynamics, geophysics, and meteorites. The workshop is limited to approximately 100 attendees. Main ...
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 ...
Summary. From the viewpoint of planet formation in the Solar System, Main Belt asteroids are the remnants of the so-called planetesimal population, the building bricks of planets that formed ubiquitously all over the Solar Nebula. Over the last years evidence has grown that planetesimals formed big from the gravitational collapse of a local ...
