https://2s.io/api/space/close-approachesGET /api/space/close-approaches · x402 API by 2s.io
List near-Earth asteroid/comet close approaches to Earth within a date window and maximum distance, from NASA JPL's Close-Approach Data API. Filter by dateMin / dateMax (YYYY-MM-DD) and distMaxAu (max approach distance in AU; default 0.05 AU ≈ 19.5 lunar distances). Each approach: object designation, close-approach date (UTC), nominal + minimum distance in AU and lunar distances, relative velocity (km/s), and absolute magnitude H (a size proxy). Sorted nearest-first. Planetary-defense, observation planning, and "what's passing by this month" queries. Public-domain NASA/JPL data; for full physical/orbital params of a listed object see /api/space/body.
