An attempt has been made to estimate the rate of destruction of the Oort cloud by stars passing through it. Two different mechanisms of cloud dispersion have been investigated. Numerical estimates show that the cumulative dispersing mechanism plays the leading role. The lower limit for the half-life of the cloud is 1.1 × 109 yr.
