The catalog of minor planets is published by the Minor Planet Center and contains more than half a million entries, including 134340 Pluto.[1] For an overview, see index.




Growing number of minor planets since 1995:

  •      numbered and named minor planets


  •      numbered but unnamed minor planets


  •      unnumbered minor planets (not part of this list)




The following is a list of numbered minor planets in numerical order. Minor planets are all small bodies in the Solar System, including dwarf planets, with the exception of comets. The catalog consists of hundreds of pages, each containing 1000 minor planets. Every month, several thousand minor planets are newly numbered by the Minor Planet Center on behalf of the International Astronomical Union (see index).[1] As of October 2018[update], there are 523,824 numbered minor planets (secured discoveries) out of a total of 789,069 observed bodies.[2][3]


The catalog's first object is 1 Ceres, discovered by Giuseppe Piazzi in January 1801, while its best-known entry is Pluto, listed as 134340 Pluto. The vast majority (97%) of minor planets are asteroids from the asteroid belt (the catalog uses a color code to indicate a body's dynamical classification). There are more than a thousand different minor-planet discoverers observing from a growing list of registered observatories. In terms of numbers, the most prolific discoverers are LINEAR, Spacewatch, MLS, NEAT and CSS. There are also 21,348 named minor planets mostly after people, places and figures from mythology and fiction.[3] Approximately 96% of all numbered catalog entries remain unnamed. The Jupiter trojan (3708) 1974 FV1 is currently the lowest-numbered unnamed minor planet.[4]


It is expected that the upcoming survey by the LSST will discover another 5 million minor planets during the next ten years—a tenfold increase from current numbers.[5] While all asteroids with a diameter above 10 kilometers have already been discovered, there might be as many as 10 trillion 1-meter-sized asteroids or larger out to the orbit of Jupiter; and more than a trillion minor planets in the Kuiper belt of which hundreds are likely dwarf planets.[5][6]

Partial lists


The list of minor planets consists of more than 500 partial lists, each containing 1000 minor planets grouped into 10 tables. The data is sourced from the Minor Planet Center (MPC) and expanded with data from the JPL SBDB (mean-diameter), Johnston's archive (sub-classification) and others (see detailed field descriptions below). For an overview of all existing partial lists, see § Main index.

The example above shows five catalog entries from one of the partial lists. The table includes the columns § Designation ,§ Discovery, and § Discoverers, giving a minor planet's permanent and provisional designation, its discovery date and location, and the officially credited discoverer, respectively. (The MPC may credit one or several astronomers, a survey or similar program, or the observatory site with the discovery.) In column "category" an object's membership to a collisional family, dynamical group or Trojan camp is displayed. The body's rounded mean-diameter () is sourced from JPL's SBDB with otherwise calculated estimates given in italics (see § Diameter). For each catalog entry, there is an external link to the MPC object page in column reference (Ref). The meaning of a minor planet's name is also linked.


In this example, all five asteroids were discovered at Palomar Observatory by a trio of astronomers: Cornelis van Houten, Ingrid van Houten-Groeneveld and Tom Gehrels. (Note: discoverers, discovery site and category are only linked if they differ from the preceding catalog entry). The background color represents a minor planet's principal orbital group—cyan is used for Jupiter trojans, while a white to grey color is for asteroids of the inner (white), central (light-grey) and outer regions (dark grey) of the asteroid belt. For more information, see § Orbital groups. In the example, one main-belt asteroid belongs to the Nysa family (NYS), while the others are from the background population, marked with "—". Column "permanent designation" displays a minor planet's number and name. While all catalog entries must have a number, 189004 Capys is the only one that has also received a name. In this column, stand-alone articles about the object are linked (in boldface; while redirects are not linked). The provisional designation in this example is an uncommon survey designation.

Top 10 discoverers of minor planets account for nearly 90% of all discoveries (as of November 2017; total of 506,410 numbered bodies; corrected MPC-figures).[7][8]



Discoverers



The MPC credits more than 1000 professional and amateur astronomers as discoverers of minor planets. Many of them have discovered only a few minor planets or even just co-discovered a single one. Moreover, a discoverer does not need to be a human being. There are about 300 programs, surveys and observatories credited as discoverers. Among these, a small group of U.S. programs and surveys actually account for most of all discoveries made so far (see pie chart). As the total of numbered minor planets is growing by the thousands on a monthly basis, all statistical figures are constantly changing. Note that the MPC summarizes the total of discoveries somewhat differently (typically by distinct group of discoverers), for example, bodies discovered in the Palomar–Leiden Survey are directly credited to the trio of astronomers as displayed in the above table.



Designation


After discovery, minor planets generally receive a provisional designation, e.g. 1989 AC, then a leading sequential number in parenthesis, e.g. (4179) 1989 AC, turning it into a permanent designation (numbered minor planet). Optionally, a name can be given, replacing the provisional part of the designation, e.g. 4179 Toutatis. (Note that on Wikipedia, named minor planets also drop their parenthesis.)


In modern times, a minor planet receives a sequential number only after it has been observed several times over at least 4 oppositions.[9] Minor planets whose orbits are not (yet) precisely known are known by their provisional designation. This rule was not necessarily followed in earlier times, and some bodies received a number but subsequently became lost minor planets. The 2000 recovery of 719 Albert, which had been lost for nearly 89 years, eliminated the last numbered lost asteroid.[10]


Only after a number is assigned is the minor planet eligible to receive a name. Usually the discoverer has up to 10 years to pick a name; many minor planets now remain unnamed. Especially towards the end of the twentieth century, large-scale automated asteroid discovery programs such as LINEAR have increased the pace of discoveries so much that the vast majority of minor planets will most likely never receive names.


For the reasons mentioned above, the sequence of numbers only approximately matches the timeline of discovery. In extreme cases, such as lost minor planets, there may be a considerable mismatch: for instance the high-numbered 69230 Hermes was originally discovered in 1937, but it was a lost until 2003. Only after it was rediscovered could its orbit be established and a number assigned.



Discovery site



Observatories, telescopes and surveys that report astrometric observations of small Solar System bodies to the MPC receive a numeric or alphanumeric code such as 675 for the Palomar Observatory, or I41 for the Palomar Transient Factory, a dedicated survey that was conducted at Palomar Observatory during 2009–2012. On numbering, such an observatory may directly be credited by the MPC as discoverer.



Orbital groups



In this catalog, minor planets are classified into one of 8 principal orbital groups and highlighted with a distinct color. These are:















  Near-Earth obj.  

  MBA (inner)

  MBA (outer)

  Centaur

  Mars-crosser

  MBA (middle)  

  Jupiter trojan 

  Trans-Neptunian obj.





The vast majority of minor planets are evenly distributed between the inner-, central and outer parts of the asteroid belt, which are separated by the two Kirkwood gaps at 2.5 and 2.82 AU. Nearly 97.5% of all minor planets are main-belt asteroids (MBA), while Jupiter trojans, Mars-crossing and near-Earth asteroids each account for less than 1% of the overall population. Only a small number of distant minor planets, that is the centaurs and trans-Neptunian objects, have been numbered so far. In the partial lists, table column "category" further refines this principal grouping:


  • main-belt asteroids show their family membership based on the synthetic hierarchical clustering method by Nesvorný (2014),[11][a]


  • resonant asteroids are displayed by their numerical ratio and include the Hildas (3:2), Cybeles (7:4), Thules (4:3) and Griquas (2:1), while the Jupiter trojans (1:1) display whether they belong to the Greek (L4) or Trojan camp (L5),[12]

  • near-Earth objects are divided into the Aten (ATE), Amor (AMO), Apollo (APO), and Atira (ATI) group,[b] with some of them being potentially hazardous asteroids (PHA)[13]

  • trans-Neptunian objects are divided into dynamical subgroups such as cubewanos, scattered disc objects, plutinos and other Neptunian resonances.[14]


  • Comet-like and/or retrograde damocloids with low TJupiter are tagged with damocloid


  • Other unusual objects based on MPC's and Johnston's list are labelled unusual

(c) This chart has been created using a classification scheme adopted from and with data provided by the JPL Small-Body Database.[8][d]


Diameter


If available, a minor planet's mean diameter (), in meters (m) or kilometers (km) is taken from the Small-Body Database. These figures were typically published by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer. Mean diameters are rounded to two significant figures if smaller than 100 kilometers. Estimates are in italics and calculated from a magnitude-to-diameter conversion, using an assumed albedo derived from the body's orbital parameters or, if available, from a family-specific mean albedo (also see asteroid family table).[e]

Notes




  1. ^ Sources for asteroid families determined by the synthetic hierarchical clustering method: for asteroids number 1 to 393,347 (D. Nesvorný 2014, Identification and Dynamical Properties of Asteroid Families), and for asteroids 393,348 to 494,645 (AstDys as of 2018, Family classification (A. Milani / Z. Knežević 2014). Following 8 families from latter were mapped to family names of former: Hertha→Nysa, Minerva→Gefion, Klytaemnestra→Telramund, Lydia→Padua, Innes→Rafita, Zdenekhorsky→Nemesis, Klumpkea→Tirela, Gantrisch→Lixiaohua, Harig→Witt. All other families at AstDys that are not listed by Nesvorný do not show an abbreviated family name with a linked "Family Identification Number" (FIN). Instead, LoMP-entries for members of these families display the number of the parent body, e.g. (5) for 5 Astraea.


  2. ^ ab Split-up of NEOs into Amor, Aten, Apollo and Atira asteroid is based on the orbital criteria given in adjunct table. The data is sourced from JPL Small-Body Orbital Elements "Numbered Asteroids (50 MB)" file


  3. ^ There are a few minor planets that remain unclassified based on the defined orbital criteria. At least five of these bodies have a semi-major axis too large to be an outer main-belt asteroid, and an orbit too eccentric to be classified as a Jupiter trojan (JPL classifies these bodies simply as "asteroids", while the MPC, which never distinguishes between inner, outer and middle MBAs, classifies them as "main-belt asteroids"). Other unclassified minor planets include Mars-crossers (as per MPC) with a semi-major axis of that of an outer-MBA (as per JPL).


  4. ^ This table adopts the orbital criteria used by the JPL Small-Body Database, with the exception of (1.) using a different limit to categorize asteroids of the intermediate main belt (i.e. a = 2.5–2.82 AU), and (2.) adding another orbital criteria to outer MBAs (q > 1.666 AU).
    The values for an object's perihelion and aphelion need to be derived from the semi-major axis and the eccentricity as they are not provided in the data source (q = a(1-e); Q = a(1+e)).



  5. ^ Diameters are calculated as a function of absolute magnitude "H" and geometric albedo as documented at CNEOS. While "H" is taken from the Ascii files at the Small Body Data Base, the assumed albedo is taken from an asteroid-family specific figure (Nesvorny, synthetic HCM v.3, as shown in table) or, alternatively – for background asteroids, Jupiter trojans, near-Earth and distant objetcs – from the body's orbital parameters (as per 2. Taxonomic Class, orbital class, and albedo at the LCDB and/or Johnston's Archive). This is: 0.20 (inner MBAs and NEOs), 0.057 (outer MBAs and Jupiter trojans), 0.10 (middle MBAs with a semi-major axis between 2.6 and 2.7 AU), 0.09 (centaurs and TNOs). The conversion formula for a given albedo (p) and abs. magnitude (H) is:
    pow(10, (3.1236 − (0.5 × log10(p)) − (0.2 × H))).

In most cases, this is about 4 to 6 months a year. Some notable minor planets are exceptions to this rule, such as 367943 Duende.
