Abstract

The dynamics of comet Tempel 1 before and after its collision with the Deep Impact space mission impactor have been studied. The historical review of observations, study of motion of the comet Tempel 1, description of the Space mission Deep Impact and results derived from its implementation are described. The numerical theory of motion of the comet Tempel 1 is obtained using three different sets of parameters. The first solution assumed that on the considered interval non-gravitational parameters were unchanged. The second solution assumed that the collision with the impactor could lead to change in the non-gravitational acceleration. The instantaneous change of comet velocity due to collision with the impactor was assumed in the third solution. The perturbation in motion of the comet Tempel 1 due to collision with the impactor is estimated using the results of the Space mission Deep Impact.
