Constraints on modified Newtonian dynamics theories from radio tracking data of the Cassini spacecraft

Jet Propulsion Laboratory, California Institute of Technology, 4800 Oak Grove Drive, Pasadena CA 91109(Dated: March 4, 2014)The MOdi ed Newtonian Dynamics (MOND) is an attempt to modify the gravitation theory tosolve the Dark Matter problem. This phenomenology is very successful at the galactic level. Themain e ect produced by MOND in the Solar System is called the External Field E ect parametrizedby the parameter Q
