SESZIONE DI TORINO
Cosmology can affect gravitational phenomena in local systems. Planet orbits, gravitational redshifts and light deflection feel both the dark energy and the dark matter filling in the universe. Actual bounds on the cosmological parameters from accurate astrometric data in the Solar system fall short of ten orders of magnitude with respect to estimates from observational cosmology but future radio-ranging measurements of outer planets could improve constraints by five orders of magnitude.
