Abstract

Using positional observations of the comet Tempel 1 from 1967 to 2010 nongravitational acceleration and instantaneous change of the comet velocity due to collision with impactor have been determined. Instantaneous change of velocity is compared with the perturbation calculated from velocity and mass of the ejected matter. Comparison of these values shows that the comet has experienced a much greater perturbation than it follows from the estimations of mass and velocity of ejected matter
