Scientific paper

Spacewatch is an exploration for asteroids and comets throughout the solar system, from the space near Earth to beyond the orbit of Neptune. Among other things, Spacewatch has reported positions of about 200,000 asteroids, mostly in the main belt, discovered seven objects beyond the orbit of Neptune, eight Centaurs between the orbits of Jupiter and Neptune, and (most relevant to this Roundtable) about 200 Earth-approaching objects since large-scale Spacewatch surveying was begun a decade ago. In addition to discovering new objects, Spacewatch determines the statistical properties of the various populations of asteroids and comets according to their orbital characteristics and absolute magnitudes. Here we use the term "Earth Approacher" (EA) to include both asteroids and comet nuclei whose orbits bring them close to the Earth at times, whether or not their orbits cross the Earth's. "Close" is defined to be within 0.3 AU, or 5 x 107 km. This term is more precise than "Near Earth Object" (NEO) or "Near Earth Asteroid" (NEA) because most of the time these objects are not "near" Earth, in the sense of a cloud following the Earth.
