Delivery of Bodies to the Earth and the Moon from the Zone of the Outer Asteroid Belt [#6040]
The probability of a collision with the Earth of a body with semi-major axis between 3 and 4 AU could be greater than that for greater semi-major axes. The zone of the outer asteroid belt could be one of the sources of the late heavy bombardment.
