We discuss the influence of the cosmological constant on the solar system dynamics. Observational constraints are derived from measurements of the periastron advance of the planets. Moreover, we consider the change in the mean motion due to . Up to now, Earth and Mars data give the best constraint, . If properly accounting for the gravito-magnetic effect, this upper limit on could greatly improve in the near future thanks to new data from planned or already operating space-missions. Dark matter or modifications of the Newtonian inverse-square law in the solar system are discussed as well. Variations in the 1/r2 behavior are considered in the form of either a possible Yukawa-like interaction or a modification of gravity of MOND type.
