At low energies, Ho\\v{r}ava gravity is characterized by three dimensionless couplings, $\\alpha$, $\\beta$ and $\\lambda$, which vanish in the general relativistic limit. Solar system and gravitational wave experiments bound two of these couplings ($\\alpha$ and $\\beta$) to tiny values, but the third remains relatively unconstrained ($0\\leq\\lambda\\lesssim 0.01-0.1$).
