In this work, the Kehagias-Sfetsos (KS) black hole in Hořava-Lifshitz gravity is probed through particle geodesics. It is found that the gravitational force of the KS black hole becomes weaker than that of Schwarzschild black hole around the horizon and interior space. Particles can be always scattered or trapped in new closed orbits, unlike those falling forever in Schwarzschild black hole. The properties of null and timelike geodesics are classified with values of coupling constants. The precession rates of the orbits are also evaluated. Furthermore, the time trajectories are classified under different values of coupling constants for both null and timelike geodesics. Physical phenomena that may be observable in our universe are discussed.
