11264 Claudiomaccone: Small binary main-belt asteroid

Planetary and Space Science, 2007
Abstract Photometric CCD observations of the small main-belt asteroid 11 264 Claudiomaccone, carried out with the 0.7-m telescope at Chuguev Observation Station (Kharkiv, Ukraine) in November 2004 and the 1-m telescope at Simeiz Observatory (Crimea, Ukraine) in December 2004, have shown the presence of two different periods in asteroid brightness ...

Main Belt Asteroid Sample Return Mission Design

46th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2010
The Dawn spacecraft is on its way to rendezvous with two main belt asteroids, Ceres and Vesta. The science community is already anticipating compelling results that would dictate a sample return mission. Asteroid sample return missions are already highlighted in the Decadal Survey and are directly solicited through the New Frontiers mission ...

Low-Cost Main-Belt Asteroid Sample Return

Journal of Spacecraft and Rockets, 2001
A main-belt asteroid sample return without landing on the asteroid is proposed. The spacecraft collects the sample during the asteroid  yby, crossing the dust cloud produced by a projectile, and delivers the sample to the Earth. To lower the launch energy, the spacecraft uses a Venus and Earth gravity assist trajectory type maneuver.

Asteroid Proper Elements and the Dynamical Structure of the Asteroid Main Belt

Icarus, 1994
Abstract 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 ...

The number density of main‐belt asteroids

Astronomische Nachrichten, 1997
AbstractIn 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

2014
Very 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 ...

Olivine-rich asteroids in the main asteroid belt

2015
Olivine-dominated asteroids, classified as A-types with near-infrared spectral measurements are largely thought to be the mantle remnants of disrupted differentiated small bodies. These A-type asteroids hold clues to asteroid differentiation and to the collisional history of those differentiated bodies.

Main Belt Asteroid Shapes from SuperWASP Photometry

2021
The SuperWASP telescope was used to search for exoplanetary transits. It also serendipitously observed Solar System Objects, with a large number of main belt asteroids being observed for at least one apparition by the telescope. Data are available for the year 2004, and then from 2006 to 2012, but data collected after 2006 has remained largely unused ...
