Low-thrust tour of the main belt asteroids [PDF]
, 2018 This work presents some initial results on a possible low-thrust tour of the main asteroid belt. The asteroids are visited through a series of fly-by’s to be completed within a given time-frame and limit on the mass of the spacecraft at launch.

Subaru Main Belt Asteroid Survey (SMBAS)—Size and color distributions of small main-belt asteroids
Planetary and Space Science, 2007Abstract Since February, 2001, we have been conducting a series of survey observations to investigate the physical property of very small Main Belt Asteroids (sub-km MBAs) using the Subaru prime-focus camera (Suprime-Cam) attached to the 8.2 m Subaru telescope. We call our surveys “SMBAS: Subaru Main-Belt Asteroids Survey”.

Polarimetry of main belt asteroids: Wavelength dependence
Icarus, 2009 New UBVRI polarimetric observations of ten asteroids, including space mission targets 1 Ceres and 21 Lutetia, are presented. These observations were obtained with the 1.25-m telescope of the Crimean Astrophysical Observatory and have been used to study the wavelength dependence of polarization for a sample of asteroids belonging to the M and low albedo

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 ...

Discovery of a Basaltic Asteroid in the Outer Main Belt
Science, 2000Visible and near-infrared spectroscopic observations of the asteroid 1459 Magnya indicate that it has a basaltic surface. Magnya is at 3.15 astronomical units (AU) from the sun and has no known dynamical link to any family, to any nearby large asteroid, or to asteroid 4 Vesta at 2.36 AU, which is the only other known large basaltic asteroid.

The Main Belt as a Source of Near-Earth Asteroids
Earth, Moon, and Planets, 1996We investigate the flux of main-belt asteroid fragments into resonant orbits converting them into near-Earth asteroids (NEAs), and the variability of this flux due to chance inter asteroid al collisions. A numerical model is used, based on collision al physics consistent with the results of laboratory impact experiments.

The recent breakup of an asteroid in the main-belt region
Nature, 2002The present population of asteroids in the main belt is largely the result of many past collisions. Ideally, the asteroid fragments resulting from each impact event could help us understand the large-scale collisions that shaped the planets during early epochs.

The number density of main‐belt asteroids
Astronomische Nachrichten, 1997AbstractIn this paper we have studied how the number density of asteroids varies as a function of the mean distance from the sun.

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 ...
