# MOND effects in the inner Solar system

@article{Milgrom2009MONDEI, title={MOND effects in the inner Solar system}, author={Mordehai Milgrom}, journal={Monthly Notices of the Royal Astronomical Society}, year={2009}, volume={399}, pages={474-486} }

I pinpoint a previously unrecognized MOND effect that may act in the inner Solar system, and is due to the galactic acceleration gg = ηa 0 : a byproduct of the MOND external-field effect. Predictions of the effect are not generic to the MOND paradigm, but depend on the particular MOND formulation at hand. However, the modified Poisson formulation, on which I concentrate, uniquely predicts a subtle anomaly that may be detected in planetary and spacecraft motions (and perhaps in other precision…
