The orbital and absolute magnitude distribution of the near-Earth objects (NEOs) is difficult to compute, partly because only a modest fraction of the entire NEO population has been discovered so far, but also because the known NEOs are biased by complicated observational selection effects.

A recently published model of the Near Earth Object (NEO) orbital-magnitude distribution (Bottke et al., 2002, Icarus 156, 399-433.) relies on five intermediate sources for the NEO population: the ν 6 resonance, the 3 : 1 resonance, the outer portion of the main belt (i.e., 2.8-3.5 AU), the Mars-cro
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
