Abstract

The ESA astrometric mission Gaia (launch in late 2011) will be able to put to test General Relativity (GR) also thanks to a differential experiment, GAREX, implemented in the form of repeated Eddington-like measurement, aiming at measuring, for the first time, the quadrupole light bending due to an oblate planet.
