Abstract: An approximate analytical solution of the equations of the physical theory of meteors is obtained for a meteoroid moving as a single body under the assumption of constant ablation parameter. The approach allows one to predict the velocity and mass of the meteoroid at any point of its trajectory. The accuracy of the solution is estimated. A numerical-analytical method of solving the equations is proposed for the case when the ablation parameter is variable. The solutions obtained by different methods with constant and variable ablation parameters are compared.

Key words: meteoroid, ablation parameter, mass loss, analytical solution.
