Minor-planet designation
number-name combination assigned to minor planets
There are three internationally standardized designations for minor planets, which are assigned by the Minor Planet Center (MPC). In order of assignment, these are:
1. an initial provisional designation, for all announced discoveries, that reflects the date of discovery;
2. a permanent designation: a catalog number assigned sequentially once the object has a securely determined orbit;
and, for a little under 2% of objects,
3. a proper name.
For clarity and cross-referencing, it is usual for astronomical sources to identify a numbered object by both its permanent and provisional designations, or by its permanent designation (number) and name, at least in tables and for first mentions in a text. Such concatenations are not in themselves official names and do not have a fixed order or punctuation.
Comets are also managed by the MPC, as are interstellar interlopers passing through the Solar System, but for them different cataloguing systems are used.
Summary
A provisional designation is automatically assigned when an object is reported to the Minor Planet Center (MPC), a branch of the International Astronomical Union, after at least two-night's observation. A permanent designation (sequential number) is assigned by the MPC once the orbital path is sufficiently secured for the object to be recoverable.
“Minor-planet designation” enters the record as number-name combination assigned to minor planets. Crown Archives preserves that source wording while asking what Minor-planet, designation and number-name can confirm, complicate or overturn.
Why this record matters
“Minor-planet designation” is worth following because a concise public description often conceals a longer documentary argument. Here, Minor-planet, designation and number-name provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 1, 2026. The linked authority identifier is Q817125. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
