Upper bound on the momentum scale in noncommutative phase space of canonical type

Abstract

We find stringent upper bound on the momentum scale in noncommutative phase space of canonical type on the basis of studies of perihelion shift of the Mercury planet with taking into account features of description of motion of macroscopic body in the space with noncommutativity of coordinates and noncommutativity of momenta. Using results for precession of perihelion of the Mercury planet from ranging to the MESSENGER spacecraft we obtain upper bound for parameter of momentum noncommutativity $10^{-80}\\textrm{kg}^2\\textrm{m}^2/\\textrm{s}^2$ which is many orders less than known in the literature.
