Abstract: We focus on Horava-Lifshitz HL theory of gravity, and, in particular, onthe Kehagias and Sfetsos s solution that is the analog of Schwarzschild blackhole of General Relativity. In the weak-field and slow-motion approximation weanalytically work out the secular precession of the longitude of the pericentreof a test particle induced by this solution. Its analytical form is differentfrom that of the general relativistic Einstein-s pericentre precession. Then,we compare it to the latest determinations of the corrections to the standardNewtonian- Einsteinian planetary perihelion precessions recently estimated byE.V. Pitjeva with the EPM2008 ephemerides. It turns out that the planets of thesolar system, taken singularly one at a time, allow to put lower bounds on theadimensional HL parameter \psi 0 of the order of 10^-12 Mercury 10^-24Pluto. They are not able to account for the Pioneer anomalous accelerationfor r > 20 AU.
