Ring torque of Saturn from interplanetary meteoroid impact

Reevaluation of the interplanetary meteoroid mass flux at 10 AU obtains a value of M≈6×10⁴ g sec^-1 for the meteoroid mass loading rate to the rings of Saturn. This meteoroid impact flux suggests that a large change to the configuration of the ring system could occur in a relatively short time ({less-than or approximate}10⁹ years). This new element thus should be taken into consideration in discussion of the dynamical evolution of the rings.
