The ESA astrometric mission Gaia, due for launch in late 2011, will observe a very large number of asteroids (~ 350,000 down to the magnitude 20), most from the main belt, with an unprecedented positional precision (at the sub-milliarcsecond level). Such high-precision astrometry will enable to considerably improve the orbits of a large number...
The Gaia satellite, an ESA cornerstone mission to be launched at the end of the year 2011, will observe a large number of celestial bodies including also small bodies of the solar system. Albeit spread from the inner to the outer regions of the solar system, these are mainly near-Earth objects and main-belt asteroids. All objects brighter than...
We present in the following some capabilities of the Gaia mission for performing local test of General Relativity (GR) based on the astrometry of asteroids. This ESA cornerstone mission, to be launched in Spring 2012, will observe---in addition to the stars and QSOs---a large number of small solar system bodies with unprecedented photometric...
The Gaia mission will observe between 2.5 and 3x105 Solar System objects. Most of them will be asteroids. As described elsewhere (Cellino et al. 2007, Tanga et al. 2007, Mignard et al. 2008) Gaia will provide a complete dynamical and physical characterisation of these bodies, that has no comparisons with the datasets ever obtained by a single...
