Work is now complete on the identification and classification of the Lunar Ribus – the Moon’s most prominent landforms, defined by ≥1,000 metres of topographic prominence.

The dataset identifies 3,670 Lunar Ribus and 11,003 Negative Lunar Ribus (typically craters). This represents the most comprehensive prominence-based catalogue of lunar relief produced to date. It is also the first prominence-based mountain list beyond Earth and the first detailed global catalogue of lunar mountains defined using a single, objective topographic criterion.

Latest version of the Lunar Ribus database:

The current release is V1. A V2 update is not expected before the end of 2026.
