Lunar 100 – Object 46
The central peak of Regiomontanus is an unusual summit that may be volcanic rather than impact‑generated. Its asymmetric shape, steep flanks, and offset position within the crater suggest it could be the remnant of a volcanic cone or uplifted intrusive feature that predates the impact. This peak is included in the Lunar 100 because it represents a possible volcanic central peak, highlighting how some crater interiors may preserve older volcanic structures later exposed by impact excavation.
