Sage, Leslie J.
- Abstract
The article discusses studies on asteroid belt which is believed to be a source of giant impact on Earth until 1.8 million years ago. The study by Brandon Johnson and Jay Melosh of Purdue University has worked on the relationship of energy and the thickness of spherule bed. Moreover, study by Bill Bottke of the Southwest Research Institute in Boulder, Colorado has found that through numerical simulations, the asteroid belt has started beyond the orbit of Mars.
