Sky monitoring projects e.g. NEAT, LINEAR, LONEOS, CSS, CINEOS, Spacewatch Near Earth asteroids and other objects to try to discover.
The International Academy of Astronautics held the first conference in 2009 (Protecting Earth from Asteroids) from Spain, in May 2011 was a further conference (From Threat to Action) in Bucharest, Romania. It was the risk analysis program NEOMiSS (The Near-Earth Object Mitigation Support System) is presented.
