Accepted Identifiers and Catalogs
The NASA Exoplanet Archive maintains its own list of cross-identifications for every object in its database.
The Explore the Archive search on the home page and on this page accept queries for single objects by name or coordinates, as well as a radius search. The search function at the top of this page also accepts a list of coordinates and objects.
If your query returns an error, check the table on this page to make sure you entered the correct name.
For more information on using the Explore the Archive search, see the Inventory Service User Guide.
Use the Correct Format In Queries
If you enter the name of a star of a multiple system, the component letters are case-sensitive. For example, the system 30 Ari B is not treated the same as 30 Ari b.
When entering a planet name, you must include a space between the star name and the planet letter. Planet letters are also case-sensitive.
For the prefixes mu/MU and nu/NU, the case does matter:
- mu/nu = Greek letter-named star in constellation
- MU/NU = variable star
Note: nu2 Lupi and nu 2 Lupi are both accepted.
The following table lists the recommended identifiers to use when looking up information on a single object in the Exoplanet Archive. See the Table Legend and Notes on this page for further instructions.

† In the LHS Catalog, some stellar entries are designated by a lower-case letter (e.g., LHS 5358b, which represents a star, not a planet). To query for a planet in such a system, use LHS NNNNa b.
Table Legend
In the instructions above:
- N = an integer digit (0-9)
- HH = an integer number of hours (00-23)
- MM = an integer number of minutes (00-59)
- m = fraction of a minute (0-9); e.g., MMm = 217 corresponds to 21.7 minutes
- SSSS or SSS = seconds plus fraction of second (0000-5999 or 000-599); e.g., SSSS = 2248 corresponds to 22.48 seconds
- DD = integer number of degrees (00-89)
- YYYY = integer number of years (2000-2099)
- A = a letter of the (English) alphabet (A-Z or a-z)
- ggg = The full Greek letter (e.g., alpha, beta) or the 3 English letter abbreviation of Greek letters (e.g., alf, bet). For the Greek letters mu (μ) and nu (ν), please repeat the last character (muu, nuu) to enforce a three-character abbreviation.
- s = "+" or "-" sign
- CON = Three-letter abbreviation of constellation name (e.g., TAU, AND). See our complete list of constellation abbreviations here.
All other letters are entered as is. Also, note that:
- Italicized = an instruction
- Anything written in [square brackets] may or may not be part of a query.
- Leading zeros (0s) may be omitted
- The Exoplanet Archive is case-sensitive only on the component and planet letters
Notes
Regarding Durchmusterung catalogs: The Exoplanet Archive uses the same designations as published in the original Durchmusterung catalogs. That is, the identifiers BD, CD, CPD, SD are not interchangeable. In the same spirit, the NASA Exoplanet Archive also does not recognize the generic Durchmusterung (DM) identifier.
Regarding SIMBAD: This search function uses SIMBAD to find coordinates for object names that are not currently in the NASA Exoplanet Archive.
