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 ...
The JPL Small-Body Database gives a running total of 676,786 unnumbered minor planets. [ 2 ] [ a ] The tables below contain 95 objects with a principal designation assigned between 1927 and 1993.
Hatfield left JPL in 1974 and the JPLDIS project was assigned to Jeb Long, another programmer at JPL, who added many advanced features plus a programming language. In 1978, while at JPL, Wayne Ratliff wrote a database program in assembly language for CP/M based microcomputers to help him win the football pool at the office. He based it on Jeb ...
The Jet Propulsion Laboratory (JPL) is a federally funded research and development center (FFRDC) in La Cañada Flintridge, California, Crescenta Valley, United States. [1] Founded in 1936 by California Institute of Technology (Caltech) researchers, the laboratory is now owned and sponsored by NASA and administered and managed by Caltech. [2] [3]
Recent citations can also be found on the JPL Small-Body Database (SBDB). [3] Until his death in 2016, German astronomer Lutz D. Schmadel compiled these citations into the Dictionary of Minor Planet Names (DMP) and regularly updated the collection. [4] [5]
Orbit simulation from NASA JPL site; Orbital details from the IAU Minor Planets Center (175113) 2004 PF115 at the JPL Small-Body Database. Close approach · Discovery · Ephemeris · Orbit viewer · Orbit parameters · Physical parameters
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 estimates that it came to perihelion (closest approach to the Sun) around the year 1888 ± 15. [3] JPL estimates aphelion (farthest distance from the Sun) to be in 2238 at 128 AU [9] whereas Project Pluto (which only fit 5 of the 8 observations) estimates aphelion was in 2015 at 86 AU. [10] As the JPL solution fits ...
