Asteroid Detection and Monitoring Using a Satellite-Borne Visible Scanner

Abstract

A satellite-borne visible scanner is proposed to continuously monitor the celestial sphere for near Earth asteroids. The proposed scanner uses the parallax motion of near Earth objects against a fixed background of distant objects. Image processing techniques will allow the detection of asteroids as small as 50 m in diameter at distances greater than 7 x 500,000 km. This will give sufficient warning time against Earth intersecting asteroids.
