List of minor planets. The catalog of minor planets is published by the Minor Planet Center and contains 720,000 entries, including 134340 Pluto. [ 1] For an overview, see index. The following is a list of numbered minor planets in ascending numerical order. With the exception of comets, minor planets are all small bodies in the Solar System ...
All other minor planets and comets are called small Solar System bodies. [1] The IAU stated that the term minor planet may still be used, but the term small Solar System body will be preferred. [8] However, for purposes of numbering and naming, the traditional distinction between minor planet and comet is still used.
Appearance. 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. [ 2 ][ 3 ] Critical list information is also provided by the MPC, [ 2 ...
This is a list of named minor planets in an alphabetical, case-insensitive order grouped by the first letter of their name. [a] [b] New namings, typically proposed by the discoverer and approved by the Working Group for Small Bodies Nomenclature (WGSBN) of the International Astronomical Union, are published nowadays in their WGSBN Bulletin and summarized in a dedicated list several times a year.
Gonggong (2007) A dwarf planet is a small planetary-mass object that is in direct orbit around the Sun, massive enough to be gravitationally rounded, but insufficient to achieve orbital dominance like the eight classical planets of the Solar System. The prototypical dwarf planet is Pluto, which for decades was regarded as a planet before the ...
The number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt [1] and over 10,000 in the region beyond. [2] However, consideration of the surprisingly low densities of many large trans-Neptunian objects, as well as spectroscopic analysis of their surfaces, suggests that the number of dwarf planets may be much lower, perhaps only nine among ...
Eris ( minor-planet designation: 136199 Eris) is the most massive and second-largest known dwarf planet in the Solar System. [ 22] It is a trans-Neptunian object (TNO) in the scattered disk and has a high- eccentricity orbit. Eris was discovered in January 2005 by a Palomar Observatory –based team led by Mike Brown and verified later that year.
List of minor-planet groups. A minor-planet group is a population of minor planets that share broadly similar orbits. Members are generally unrelated to each other, unlike in an asteroid family, which often results from the break-up of a single asteroid. It is customary to name a group of asteroids after the first member of that group to be ...
