Cosmologically motivated theories that explain small acceleration rate of the Universe via modification of gravity at very large, horizon or super-horizon distances, can be tested by precision gravitational measurements at much shorter scales, such as the Earth-Moon distance. Contrary to the naive expectation the predicted corrections to the Einsteinian metric near gravitating sources are so significant that fall within sensitivity of the proposed Lunar Ranging experiments. The key reason for such corrections is the van Dam-Veltman-Zakharov discontinuity present in linearized versions of all such theories, and its subsequent absence at the non-linear level ala Vainshtein.

Beyond the Cosmological Standard Model (2014, unknown): “In the context of DGP it can be shown [882, 883, 885] that the cubic galileon leads to an angular precession in a planetary orbit of 3c/(8rc) = 25(1 Gpc/rc) μas/yr, independent of the mass and orbital radius of the planet.”
Massive Gravity (2014, methodology): “For the Earth-Moon system, taking Λ(3)3(m (2)MPl) with m ∼ H0 ∼ 10−33 eV, this leads to an anomalous precision of the order of [215] δφ ∼ 10−12 rad/orbit , (11.”
