EARTH'S PECULIAR NEIGHBORS
An asteroid heading toward Earth makes a good movie plot, but
astronomers haven't yet found any heavenly bodies on such a
collision course. There are plenty of asteroids in our neighborhood
of the solar system, however, and a team of physicists has now
discovered several new types of near-Earth-asteroid orbital motion.
In the 27 September PRL they describe their theory and computer
simulations of the orbits of three known asteroids. They conclude
that although we are safe from collisions with such objects, there
may be many asteroids inhabiting these newly discovered orbits,
including undiscovered satellites of Earth.
