Francesco Manca of the Sormano Astronomical Observatory is doing some of the important work of keeping track of the asteroids which can make close approaches to our Earth, our Moon, and other objects in space. He has compiled the fact that the asteroid hunting community has found more than 2000 small asteroids, of less than several football fields in diameter, which can make close approaches to us. Nearly 700 have orbits which allow them to come closer to the Earth than our Moon. So far more than 250 of these small asteroids have come or are predicted to come less a lunar distance from our home planet.
