We use the planetary ephemeris INPOP17b to constrain the mass of the graviton in the Newtonian limit .
We also give an interpretation of this result for a specific case of fifth force framework .
We find that the residuals for the Cassini spacecraft significantly ( 90 % C.L . )
degrade for Compton wavelengths of the graviton smaller than 1.83 \times 10 ^ { 13 } km , corresponding to a graviton mass bigger than 6.76 \times 10 ^ { -23 } eV / c ^ { 2 } .
This limit is comparable in magnitude to the one obtained by the LIGO-Virgo collaboration in the radiative regime .
We also use this specific example to illustrate why constraints on alternative theories of gravity obtained from postfit residuals are generically overestimated .
