Abstract
The proposed baseline GAIA mission will be able to detect the astromet ric signature of Jupiter-size planets around of the order of a million stars, using either global or narrow-angle astrometry. If the mission can realize the higher astrometric accuracy that photon statistics al lows for bright stars, lower-mass planets (from Earth size to ten time s larger) can be found around ten to a few hundred stars.
