It is expected that the upcoming survey by the Vera C. Rubin Observatory will discover another 5 million minor planets during the next ten years—almost a tenfold increase from current numbers.[5] While all main-belt asteroids with a diameter above 10 km (6.2 mi) have already been discovered, there might be as many as 10 trillion 1 m (3.3 ft)-sized asteroids or larger out to the orbit of Jupiter; and more than a trillion minor planets in the Kuiper belt.[5][6] For minor planets grouped by a particular aspect or property, see § Specific lists.
Description of partial lists
The list of minor planets consists of more than 600 partial lists, each containing 1000 minor planets grouped into 10 tables. The data is sourced from the

Designation
After discovery, minor planets generally receive a
In modern times, a minor planet receives a sequential number only after it has been observed several times over at least 4 oppositions.[8] 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.[9] 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 these reasons, 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 lost until 2003. Only after it was rediscovered could its orbit be established and a number assigned.

Notes
- hierarchical clustering method. The first one, Identification and Dynamical Properties of Asteroid Families (D. Nesvorný, 2014), is used for asteroids up to number 393,347. The second one is from the Asteroid Dynamic Site (AstDyS) and covers the individual asteroid family membershipfor bodies above that number (A. Milani, Z. Knežević, 2014), including all listed bodies that have been numbered since last publication in 2018. 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 not listed by Nesvorný at AstDyS do not show an abbreviated family name with a linked "Family Identification Number" (FIN). Instead, listed entries for such members give the designation of their parent body, e.g. (5) for 5 Astraea.

- ^ 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).
- aphelion need to be derived from the semi-major axis and the eccentricityas they are not provided in the data source (q = a(1-e); Q = a(1+e)).
- background asteroids, Jupiter trojans, near-Earth and distant objects – 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), 0.14 (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 and abs. magnitude is: pow(10, (3.1236 − (0.5 × log10(p)) − (0.2 × H))).
