This work analyzes in some detail the feasibility of testing with astrometric measurements the hypothesis that Quantum Vacuum can have gravitational effects, as suggested in a series of recent papers ([3, 6, 5]). In particular, the possibility of detecting an excess shift of the longitude of the pericenter in the orbit of the trans-neptunian system UX25 and its satellite is investigated. The excess shift which might be experimented by the orbit of the satellite was estimated, under reasonable working hypothesis, to be about 0:23 arcsec per orbit. Several observing scenarios are explored here, including those using conventional and adaptive optics telescopes from ground, and some spaceborne telescopes.
