International Asteroid Warning Network
IAWN is a world-wide planetary defense collaboration of organizations and individual astronomers recommended by United Nations resolution who collectively work to detect, monitor, and characterize potentially hazardous asteroids and Near-Earth Objects (NEOs). If an asteroid threat were ever identified, IAWN would act as a centralized hub for disseminating information to governments to aid with analysis of impact consequences and with planning of mitigation response options.
