The era of high-precision astrometry has dawned upon us. The potential of Gaia μas-level precision in positional measuraments is about to be unleashed in the field of extrasolar planetary systems. The Gaia data hold the promise for much improved global characterization of planetary systems around stars of all types, ages, and chemical composition, particularly when synergistically combined with other indirect and direct planet detection and characterization programs.
