Query: Quantum gravity, minimum length and Keplerian orbits   We conjecture that the modified commutation relations suggested in the
context of quantum gravity (QG) persist also in the classical limit, if the
momentum of the classical object is not too large, and calculate the
corresponding perihelion precession rate for Keplerian orbits.
