Some have suggested that by pointing a stick with its end pointed into the palm of your hand that you can get yourself zapped by one of these asteroids. Maybe meteorites will work too.

All planets spin. That spin force is somehow sucking asteroids up from the bottom of the solar system. You can check out the grace gravity mission and the Mayan calendar to find the important gravity belts. As for the modern science they are called predicted asteroids. Hope that helps
