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 ...
If available, a minor planet's mean diameter in meters (m) or kilometers (km) is taken from the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, which the Small-Body Database has also adopted. [21] Mean diameters are rounded to two significant figures if smaller than 100 kilometers.
The article name contains diacritics (e.g. 2867 Šteins) - JPL Small Body Database does not support diacritics. In this case, use {{JPL small body|id=2002867}} The article name contains apostrophes (e.g. 21774 O'Brien) - a bug in the MediaWiki urlencode function results in a malformed external link. In this case, use {{JPL small body|id=2021774}}.
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]
Landed; returned dust samples to Earth in 2010 - first sample return mission from asteroid; smallest asteroid visited by a spacecraft, first asteroid visited by a non-NASA spacecraft. 2867 Šteins: 4.6: 1969 Rosetta: 2008 800 302 Flyby; first asteroid visited by the ESA. 21 Lutetia: 120 × 100 × 75 (100 km) 1852 Rosetta: 2010 3,162: 64.9
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. Additional partial lists cover the period from 1994 to 2004.
The following is a partial list of minor planets, running from minor-planet number 1 through 1000, inclusive. The primary data for this and other partial lists is based on JPL 's "Small-Body Orbital Elements" [ 1 ] and data available from the Minor Planet Center .
DE431 (JPL small-body perturber ephemeris: SB431-BIG16) better models the gravitational perturbations of the planets and includes the 16 most massive main-belt asteroids. [12] In April 2021, Sentry transitioned to DE441 which removed the very low impact probability of short-arc 2014 MV67 which had been less than 1:1-billion.
