Constraints on MOND theory from radio tracking data of the Cassini spacecraft

Understand

The MOdified Newtonian Dynamics (MOND) is an attempt to modify the gravitation theory to solve the Dark Matter problem.

• This phenomenology is very successful at the galactic level.
• The main effect produced by MOND in the Solar System is called the External Field Effect parametrized by the parameter $Q_2$.
• We have used 9 years of Cassini range and Doppler measurements to constrain $Q_2$.
