We examine the dynamics of a sample of 117 near-Earth objects (NEOs) over a time scale of 60 Myr. We find that while 10-20% end their lifetimes by striking a terrestrial planet (usually Venus or Earth), more than half end their lives in a Sun-grazing state, and about 15% are ejected from the Solar S

β¦ Synopsis
In the past three years the Spacewatch program at the University of Arizona's Lunar and Planetary Laboratory has discovered ~45% of the new Earth Approaching asteroids and found evidence for an unheralded population of small (wlOm> objects in the inner solar system. This success is due to the automated Moving Object Detection Program (MODP) which searches successive scans over the sa.me region for objects showing consistent motion. Highlights of recent discoveries, an update on research, and. the development and potential of the new 1.8m Spacewatch facility will be discussed.
