Analysis of Astrometry and Photometry Observations of Asteroids at the RTT150

Abstract

The space astrometric mission Gaia, a cornerstone of the European Space Agency, will be launched in 2012 with the objective to make a 3D precise map of our Galaxy. The Gaia will furnish positions, distances and motions of a billion stars with unprecedented precision. Beside stars, the Gaia will observe asteroids with unprecedented precision from 0.5 to 3 mas, allowing the extremely fine orbit determinations (Tanga et al., 2008). This precision has great significance for the determination of small effects influencing the dynamics (relativistic, gravitational, non-gravitational, etc.) of Solar system bodies. The determination of masses of a hundred asteroids with a relative precision better than 50% is expected in 5 years of Gaia operation (Mouret et al, 2007).
