NASASBDB Close Approaches

Query NASA's Close Approach Data (CAD) API for asteroids and comets making close approaches to Earth or other planets. Returns upcoming or historical close approaches with distances, velocities, and object properties. Useful for planetary defense research, monitoring near-Earth objects, and studying asteroid flybys. Distance units: AU (1 AU = 149.6 million km). Minimum distance 0 (impact), typical close approaches < 0.05 AU.
