Wouldn't P9 also exert gravitational perturbations on Neptune and maybe even Uranus? Even if these effects are tiny, wouldn't we nonetheless be able to see them in the data (simply because we observed those planets for a very long time, thus determining their ephemerides with very high level of accuracy)?
