We show that the inferred properties of the meteor CNEOS-2014-01-08 (IM1) canbe naturally explained by tidal disruption of rocky planets on highly eccentricorbits around the most common stars, M-dwarfs. Rocky planets can develop a highorbital eccentricity as a result of a secular torque from an outer giant planetor a binary companion. Melting of their rocky crust during many tight periapsepassages may result in additional elemental differentiation, leading toenhanced abundances of beryllium, lanthanum and uranium in the crust, asinferred from the composition of unique spherules along IM1's path. The excessenergy imparted to the tidal stream in highly eccentric orbits naturallyaccounts for the inferred IM1 speed of $\sim 60~{\rm km~s^{-1}}$ relative tothe Local Standard of Rest. Finally, the tidal disruption of $\sim 10M_\oplus$reservoirs of rocky material around M-dwarfs accounts for an impact rate of500kg meteors on Earth of once per decade, consistent with IM1.
