find should help astronomers determine how much dust in the solar system originates in
asteroid collisions; such impacts may also create fragments that reach Earth as
small meteorites.

finds smaller and more distant
asteroids, astronomers have identified clusters of similar - looking bodies clumped in analogous orbits.

finding the
smaller ones like the Tunguska impactor.
The reason I stuck with it is that it's hard to
find a demographer or other expert on population and social trends who sees even a
small chance of humankind's peaking at anything lower than nine billion — barring some catastrophic epidemic or
asteroid strike.
