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 ...
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 ...
Jet Propulsion Laboratory Development Ephemeris (abbreviated JPL DE (number), or simply DE (number)) designates one of a series of mathematical models of the Solar System produced at the Jet Propulsion Laboratory in Pasadena, California, for use in spacecraft navigation and astronomy. The models consist of numeric representations of positions ...
NASA launches exoplanet-hunting satellite TESS. Transiting Exoplanet Survey Satellite ( TESS) is a space telescope for NASA 's Explorer program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. [6] It was launched on 18 April 2018, atop a Falcon 9 launch vehicle and ...
A number of astronomers, most notably Alan Stern, the head of NASA's New Horizons mission to Pluto, contend that the IAU's definition is flawed, and that Pluto and Eris, and all large trans-Neptunian objects, such as Makemake, Sedna, Quaoar, Gonggong and Haumea, should be considered planets in their own right.
The NASA/IPAC Extragalactic Database ( NED) is an online astronomical database for astronomers that collates and cross-correlates astronomical information on extragalactic objects (galaxies, quasars, radio, x-ray and infrared sources, etc.). NED was created in the late 1980s by two Pasadena astronomers, George Helou and Barry F. Madore.
The Planetary Data System ( PDS) is a distributed data system that NASA uses to archive data collected by Solar System missions. The PDS is an active archive that makes available well documented, peer reviewed planetary data to the research community. [1] The data comes from orbital, landed and robotic missions and ground-based support data ...
The SAO/NASA Astrophysics Data System ( ADS) is an online database of over 15 million records of publications developed by the National Aeronautics and Space Administration (NASA) on astronomy and physics. Abstracts are freely available for most articles, and fully scanned articles may be available in Graphics Interchange Format (GIF) and ...
