It has been suggested that a gravitational slingshot from the hypothetical Planet 9 (P9) could explain the unusually large velocity of meteor CNEOS 2014-01-08. I show that this explanation does not work because P9 can at most provide an insignificant 0.25 km/s of the object's 42 km/s asymptotic heliocentric velocity and at most a 7.6 degree deflection due to P9's low orbital speed and non-zero radius. Furthermore, the hypothesis requires an encounter with two planets that is trillions of times more unlikely than CNEOS 2014-01-08 simply being fast from the beginning.
