Lunar Nomenclature Database

A sortable compendium of all known and named significant craters, mountains, rilles, scarps, valleys and other geographical features on the Moon.

All columns are sortable – either alphabetically (A-Z or Z-A) or numerically (ascending or descending) – by clicking the ▲ arrow at the top of the column.

Looking for a specific feature or entry? Use the Search tool located above the database.

You may print the database, in part or in full, by clicking the PRINT icon above the database.

You may export the database, in part or in full, by clicking the Excel, CSV or Copy icon above the database. (Clicking Copy copies the data to your clipboard in raw text form.)

PRO TIP 1: When searching, a partial word (such as “dan“) will find all features with that include those letters in sequence (such as “Daniel,” “Daniell,” “Cardanus,” “Danjon,” “Danish,” etc.

PRO TIP 2: Searching “lacus” will find all lakes on the Moon. Searching “rima” will find all rimae (linear rilles, or fissures) on the Moon, etc.

FEATURE NAME: The entity – usually a person – after which the feature was named (or designated). In several cases, a significant (large) crater has numerous smaller “satellite” craters adjacent to it that are named for the same entity, but with a letter (A-Z) or symbol (such as β or δ) appended to it.
† [DAGGER] – A feature name followed by a † [dagger] signifies that the designation is not considered official, but may be generally accepted. In some instances, it denotes that a designation was removed or vacated in order to be reassigned with a new designation.
– An asterisk (*) denotes that the designation is honorary.
DIA – The estimated diameter of the feature (if available) in kilometers. If no value is shown – such as 0.00 km – it does not necessarily mean that the diameter is zero; it can mean that no valid measurement is available.
LAT – The estimated latitude at the center center of the feature.
LON – The estimated longitude at the approximate center of the feature.
ORIGIN – A brief overview of who (or what) the feature was named to honor. For example, if the designation is for a person, that person’s last name appears in the Feature Name column, with their given name, birth/death dates, and a synopsis of their achievements in the Origin section.
– A tilde (~) in the Origin section shows the placement of the last name (surname), Latinized or honorific name in the given name of the person for whom the Feature Name was designated. For example, in the Origin section for the crater named Wolff, the tilde in “Christian, Baron von ~” denotes where “Wolff” appears in the honoree’s full name.
