Useful Links

The below are useful places to get more data about asteroids and their properties.
  • Minor Planet Center – The International Astronomical Union's repository for receiving and distributing positional measurements of minor planets, comets and other irregular natural satellites of major planets.  They announce discoveries of and provide identification of minor planets.  Some of their additional resources include ephemeris and the Light Curve Data Base.
  • JPL Solar System Dynamics / Horizons – The JPL solar system dynamics website provides information about orbits, physical characteristics and discovery circumstances for known natural bodies in orbit around the sun.
  • Center for NEO Studies at JPL – Provides information about close approaches, impact risks and orbits of Near Earth Objects.
  • Lowell Asteroid Services – Provides excellent services for asteroid observers, including ephemeris, lists of asteroids in need of observations and tools to generate tables of objects that are observable.
  • NASA's Planetary Data System Small Bodies Node Ferret - A search tool for the Small Bodies data hosted at the Planetary Data System.
  • The Near-Earth Asteroids Data Base (EARN) – A database of physical and dynamical properties of Near Earth Asteroids sponsored by DLR and ESA.
  • Near Earth Objects - Dynamic Site (NEODyS) -  Provides information and services for Near Earth Asteroids including estimates of close approaches and NEA orbital elements.
  • Database of Asteroid Models from Inversion Techniques (DAMIT) - Database of asteroid shape models.
  • 3D Asteroid Catalog – An interactive catalog that contains 3D models, orbital and physical parameters of Asteroids
  • NEOSurvey – A Warm Spitzer Exploration Science program that observes NEOs, provides flux density measurements and thermal modeling results.  (The results available prior to May 2016 have been incorporated into neoproperties version 2016.7.)
  • NEO Coordination Centre (ESA) – Provides information about orbits, physical characteristics and close approaches.
