We compute the static contribution to the gravitational interaction potentialof two point masses in the velocity-independent five-loop (and 5thpost-Newtonian) approximation to the harmonic coordinates effective action in adirect calculation. The computation is performed using effective field methodsbased on Feynman diagrams in momentum-space in $d = 3 - 2\varepsilon$ spacedimensions. We also reproduce the previous results including the 4thpost-Newtonian order.
