We showed that it is feasible to measure the mass of a single star by observing the variation of gravitational deflection caused by the orbital motion of the Earth. For stars within 60 pc with an appropriate background source within 1 arcsec, their mass can be measured by measuring the deflection shift with the accuracy of 10 micro arcsec. Feasibility of observing the image motion of the microlensing phenomena is also discussed.
