The huge amount of astrometric and photometric data expected by Gaia observations will contain much information on the physical characteristics and past history of the Solar System bodies. For example, Gaia astrometry and photometry of asteroids will provide useful constraints on shapes, masses, spin properties, taxonomy and presence of satellites. In this context, a refinement of our understanding of the collisional evolution and the internal properties of minor bodies can be achieved. The astrometry of several satellites orbiting the main planets gives access to their dynamical properties with an unprecedented accuracy. Masses of several asteroids will be available and a measurement of the Yarkovsky force can probably be obtained. Hints on the physical structure of the Galilean satellites of Jupiter will be derived from the measurement of dissipative (tidal) effects. On a longer term, Earthbased observation of Solar System bodies should also be positively affected by the availability of precise asteroids orbits and star positions, allowing, for example, to predict systematic observations of star occultations by minor bodies with a high rate of success.
