Near-Earth asteroids (NEAs), are a population of objects on orbit around the Sun that cross or come near that of Earth. They represent remnants of material from the early Solar System that never accreted into planets. NEAs are of special interest to us because of the special risks some of them may present to Earth from collision.
Learn more about Near Earth Asteroids and related space missions from Dr. Michael Busch, SETI Institute research scientist. Dr Busch will review the near-Earth population, as well as efforts to discover and characterize NEAs from the ground. He will also discuss past, current, and future missions to near-Earth asteroids. These include missions by NASA, ESA, JAXA, the Chinese National Space Agency, and other groups.
