Cosmogony of the asteroidal belt
Nature, 1974In the plot of asteroids considered the mass density is substituted for the number density. This approach provides a better definition of the limits of the main belt, and demonstrates more clearly that the asteroids, like the Saturnian rings, have condensed from partially corotating plasma.

A Population of Comets in the Main Asteroid Belt
Science, 2006Comets are icy bodies that sublimate and become active when close to the Sun. They are believed to originate in two cold reservoirs beyond the orbit of Neptune: the Kuiper Belt (equilibrium temperatures of ∼40 kelvin) and the Oort Cloud (∼10 kelvin).

Asteroid Proper Elements and the Dynamical Structure of the Asteroid Main Belt
Icarus, 1994Abstract We have computed proper elements for 12,573 asteroids, including all the ones with orbits accurate enough to be useful for family identification. This was done with an upgraded version of our iterative analytical algorithm, resulting in significantly improved accuracy for most asteroids in the low to moderate inclination and eccentricity ...

Structure of the Asteroid Belt for Small Members
Celestial Mechanics & Dynamical Astronomy, 1993Widely accepted recognition of the belt asteroids is that they are part of a proto-planet that could not grow up to the planetary size probably due to the gravitational perturbations by Jupiter, and asteroids are fragments produced as a result of mutual collisions (Wetherill, 1989).

1996
In 1772, Johann Titius, a German astronomer, came to Johann Bode at the Berlin Observatory with a simple mathematical relationship he had discovered that appeared to give the orbits of the planets. He pointed out that if you start with the series 0, 3, 6, 12, 24,..., add four to each, then divide by 10 you get the distance to each of the planets in ...

Formation of the Kirkwood Gaps in the Asteroid Belt
Celestial Mechanics, 1984In the framework of the restricted circular and planar 3-body problem the 2/1, 3/1 and 5/2 resonances of the asteroids belt are explored. The adiabatic invariant theory proposes that the gaps emerge during the slow dissipation of the solar nebula.

Rogue Asteroids in the Inner Main Asteroid Belt
2014Very red featureless asteroids (spectroscopic D-types) are common among Jupiter Trojans, Hildas, and the outer main belt, and are thought to have formed in the outer solar system. Dynamical models of planetary migration and orbital drift by the Yarkovsky effect predict these D-types could have been transported as close to the sun as the middle main ...

Mass distribution in the asteroid belt
Earth, Moon, and Planets, 1992The dependence of the cumulative number of numbered asteroids (up to 3720) on their absolute magnitude is investigated. The differential mass index k is derived from these relations for fainter asteroids. A steeper slope (2.2 < k < 2.4) is found in the four most populous asteroid familes (Flora, Koronis, Eos and Themis) and a flatter slope (1.3 < k < 1.
