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).
inner main-belt (a < 2.5 AU) intermediate main-belt (2.5 AU < a < 2.82 AU) outer main-belt (a > 2.82 AU) A plot of inner solar system asteroids and planets as of 2006 May 9, in a manner that exposes the Kirkwood gaps. Similar to the position plot, planets (with trajectories) are orange, Jupiter being the outer most in this view.
There are also 23,542 named minor planets mostly after people, places and figures from mythology and fiction, [4] which account for only 3.8% of all numbered catalog entries. (4596) 1981 QB and 669588 Pazura are currently the lowest-numbered unnamed and highest-numbered named minor planets, respectively. [1] [4]
Jan 1, 2014 · The P asteroids peak at about 4 AU, and the D asteroids at 5.2 AU; they are probably richer in low-temperature materials such as carbon compounds, complex organics, clays, water, and volatiles and represent the transition between the rocky asteroids of the main belt and the volatile-rich comets in the Kuiper Belt and the Oort Cloud.
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 ...
