JPL Horizons On-Line Ephemeris System provides access to key Solar System data and flexible production of highly accurate ephemerides for Solar System objects. Osculating elements at a given epoch (such as produced by the JPL Small-Body Database ) are always an approximation to an object's orbit (i.e. an unperturbed conic orbit or a " two-body ...
JPL uses the ephemerides for navigation of spacecraft throughout the Solar System. Typically, a new ephemeris is computed including the latest available observations of the target planet(s), either for planning of the mission(s), or for final contact of the spacecraft with the target. See below, Recent ephemerides in the series.
Official naming citations of newly named small Solar System bodies are approved and published in a bulletin by IAU's Working Group for Small Bodies Nomenclature (WGSBN). [1] Before May 2021, citations were published in MPC's Minor Planet Circulars for many decades. [2] Recent citations can also be found on the JPL Small-Body Database (SBDB). [3]
The JPL Small-Body Database (SBDB) is an astronomy database about small Solar System bodies.It is maintained by Jet Propulsion Laboratory (JPL) and NASA and provides data for all known asteroids and several comets, including orbital parameters and diagrams, physical diagrams, close approach details, radar astrometry, discovery circumstances, alternate designations and lists of publications ...
Bonnie J. Buratti (born 1952), American senior research scientist at the Jet Propulsion Laboratory, studies photometric properties of the surfaces of outer planet natural satellites and the small bodies of the solar system. She is a member of the science teams for the Clementine, Deep Space 1, Cassini–Huygens and New Horizons missions. JPL ...
Standish worked on the Jet Propulsion Laboratory Development Ephemeris.. Early versions refined the accuracy of these fundamental astronomical data-sets by including many recent and accurate observational data, new types of data, using improved data processing methods, including refined equations of motion which more accurately described the actual physics of the solar system.

Analysis has shown that solar-radiation pressure is perturbing its motion perceptibly. [19] However, Paul Chodas in JPL's Solar System Dynamics Group suspects that the perturbations are consistent with expectations for a rocky object but not with old flight hardware. [19] One hypothesis is that the object is a piece of lunar rock ejected by an ...
