TL;DRAbstract

The gravitational action of either dark energy or a smooth matter component filling in the universe can affect the orbits in a stellar system. Changes are related to the acceleration of the cosmological scale size. Actual bounds on the cosmological deceleration parameters from accurate astrometric data fall short of ten orders of magnitude with respect to estimates from observational cosmology but future radio-ranging measurements of outer planets in the Solar system could improve actual bounds by five orders of magnitude. Limits on either local dark matter or deviations from the gravitational Newton's law can be derived as well.
