About this product
- DescriptionNear Earth Objects (NEOs), asteroids and comets, are the closest neighbors of the Earth-Moon system. They allow research t yet possible on more distant bodies. The IAU Symposium 236 focused on the specific observation and modeling techniques for NEOs, including radar, exploration by spacecraft, measurement of n-gravitational perturbations; also on the next generation surveys expected to increase a hundred-fold the NEO discovery rate. With data from first generation NEO surveys, we w understand how they formed and evolve, dynamically and physically, opening a window on the universal astrophysical phemen of collision, leaving clear markings on the surfaces of planets, including the Earth. NEOs with orbits crossing that of the Earth are also a source of impact risks and potential NEO collisions with the Earth represent a long term threat. Mankind has to put in place a chain of mitigating actions; NEO astromers have successfully put in place the first link.
