  NASA Near Earth Object Web Service (NeoWs) REST API for searching and browsing
  near Earth asteroid information. Users can search for asteroids based on their
  closest approach date to Earth, look up a specific asteroid by NASA JPL small
  body (SPK-ID), and browse the overall dataset. Data originates from the NASA
  JPL Asteroid team and is maintained by the SpaceRocks Team.

    description: >
      RESTful web service providing near Earth asteroid information from the NASA
      JPL Asteroid team. Exposes three endpoints: a date-range feed of close
      approach events (max 7-day window), a per-asteroid lookup by SPK-ID, and a
      paginated browse of the complete NEO dataset. Each asteroid record includes
      estimated diameter, hazardous classification, orbital data, relative
      velocity, and miss distances in multiple units.
