Asteroid Close Approaches API
Live near-Earth object close approaches as an API, straight from NASA/JPL's Close-Approach Data (CAD) system. List the asteroids and comets passing nearest Earth over the next N days (or look back), with the approach date, miss distance (in astronomical units, lunar distances and kilometres), relative velocity and an estimated diameter from the object's absolute magnitude; or pull the full close-approach history for a specific object (e.g. 99942 Apophis, 101955 Bennu). Ideal for planetary-defense dashboards, astronomy & space apps, education and "asteroid of the week" content.
