Our Mission

IAWN was established (2013) as a result of the UN-endorsed recommendations for an international response to a potential NEO impact threat, to create an international group of organizations involved in detecting, tracking, and characterizing NEOs. The IAWN is tasked with developing a strategy using well-defined communication plans and protocols to assist Governments in the analysis of asteroid impact consequences and in the planning of mitigation responses.

Currently, IAWN includes members from Europe, Asia, South and North America.

ZTF Discovers a New Class of Solar System Object: 2020 AV2

(09 Jan 2020) On 4 January, 2020, the Zwicky Transient Facility team discovered a new fast-moving object and reported it immediately to the Minor Planet Center (MPC). Once posted on the MPC's NEO Confirmation Page, other observers from around the world measured the object's position on the sky. These measurements facilitated a precise fit to the object's fascinating orbit.
