Summary:
Binary asteroids -- two rocky objects orbiting about one another -- appear to be common in Earth-crossing orbits, astronomers using the world's two most powerful astronomical radar telescopes report. And it is probable, they say, that these double asteroid systems have been formed as a result of gravitational effects during close encounters with at least two of the inner planets, including Earth.
