The International Asteroid Warning Network (IAWN) is a worldwide planetary defense collaboration of organizations and astronomers that works to detect, monitor, and characterize potentially hazardous asteroids and Near-Earth Objects (NEOs). Established in 2014, IAWN serves as a central hub for disseminating information to governments to aid in analyzing impact consequences and planning mitigation responses, using well-defined communication plans and protocols. It comprises a partnership of scientific institutions, observatories, and other parties performing observations, orbit computation, and modeling related to the impact potential and effects of asteroids. IAWN collaborates with entities like the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) and the Space Mission Planning Advisory Group (SMPAG).
