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 ...
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 ...
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).
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.

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 ...
Jan 10, 2012 · Moreover, the computed P/Read intrinsic average impact probability within the main belt is about 3.48 × 10 18 km 2 yr and the average impact velocity is about 3.7 km s-1. These values are computed according to the Bottke et al. main belt population, and following the procedure described in the work of Marchi et al. . The derived projectile ...
