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.
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.
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]
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 ...
C/2024 G3 (ATLAS) is a partially disintegrated non-periodic comet, which reached perihelion on 13 January 2025, at a distance of 0.09 AU (13 million km) from the Sun.It is currently the brightest comet of 2025, [6] with an apparent magnitude reaching −3.8 on the day of its perihelion. [5]
The predominant source of JPL's financial support is NASA. [69] As a field center of NASA, JPL's primary activities and projects are generally aligned with NASA's mission objectives in space exploration, Earth sciences, and astrophysics. The funding allocated to JPL comes as a portion of NASA's annual budget, which is itself part of the United ...
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.
