NASA/JPLNEO monitoring

NASA/JPLThe following chart shows the cumulative number of known Near-Earth Asteroids (NEAs) versus time. Totals are shown for NEAs of all sizes, those NEAs larger than ~140m in size, and those larger than ~1km in size.

IAUThe single worldwide location for receipt and distribution of positional measurements of minor planets(asteroids), comets and outer irregular natural satellites of the major planets.
