The **International Asteroid Warning Network (IAWN)** is a pivotal global collaboration dedicated to detecting, monitoring, and characterizing near-Earth objects (NEOs) that could potentially threaten Earth. Established following a United Nations resolution in 2013, IAWN brings together over sixty institutions from around the world, including space agencies, universities, and private organizations[1][2]. This network is crucial for planetary defense, serving as a centralized hub for disseminating information about NEOs to governments, aiding in the analysis of impact consequences and planning mitigation responses[5]. ### History and Establishment IAWN was recommended by the Working Group on Near-Earth Objects of the United Nations Committee on the Peaceful Uses of Outer Space. The UN General Assembly endorsed its establishment through Resolution 68/75, although the exact date of this resolution is noted as December 16, 2023, in some sources, which seems to be an error given the initial setup in 2013[3][6]. NASA plays a significant role in coordinating IAWN, facilitating semi-annual meetings and leading campaigns to test the network's capabilities[2]. ### Key Achievements IAWN has fostered international collaboration among astronomers and space agencies, ensuring a unified approach to NEO detection and tracking. It has organized practice observing campaigns to simulate responses to potential asteroid threats, enhancing global preparedness[2]. Additionally, IAWN maintains an internationally recognized clearinghouse for NEO observations, providing a global portal for accurate information on NEOs[1][3]. ### Current Status Currently, IAWN has 55 signatories from 25 countries, representing a diverse range of organizations[2]. The network continues to expand with new signatories and participates in simulated asteroid impact scenarios to refine its response strategies[5]. IAWN also provides critical notifications about potential impactors, such as Asteroid 2024 YR4, ensuring timely information dissemination to governments and the public[5]. ### Notable Aspects IAWN's role
