Definition
Mons Delisle is a name that has appeared in limited astronomical references, purportedly designating a mountainous landform on a planetary body such as the Moon or Mars. No widely recognized or officially sanctioned entry for this feature exists in the primary databases of the International Astronomical Union (IAU) or major planetary science catalogs.
Overview
The term “Mons” is the Latin word for “mountain” and is used in planetary nomenclature to label isolated or prominent elevations on the surfaces of celestial bodies. “Delisle” likely references the French cartographer and astronomer Joseph-Nicolas Delisle (1688–1768), after whom the lunar crater Delisle is officially named. If Mons Delisle does indeed exist, it would presumably be situated near the Delisle crater or in a region historically associated with Delisle’s contributions to astronomy. However, the absence of a formal IAU designation or inclusion in standard planetary atlases means that the existence, location, and characteristics of Mons Delisle are not verified.
Etymology / Origin
- Mons: Latin for “mountain,” used in planetary naming conventions.
- Delisle: Derived from the surname of Joseph‑Nicolas Delisle, a noted 18th‑century French astronomer and cartographer. The lunar crater Delisle, established by the IAU in 1935, bears his name. The coupling of “Mons” with “Delisle” suggests an intended tribute to the same individual.
Characteristics
Accurate information is not confirmed. Consequently, specific data such as elevation, coordinates, geological composition, age, or observational history are unavailable. If the feature were recognized, it would likely be characterized by:
- A relief distinct enough to merit a separate designation from nearby craters or plains.
- Potential volcanic or impact‑related origin, common among named “Mons” features on the Moon and Mars.
- Inclusion in high‑resolution lunar or planetary mapping missions (e.g., Lunar Reconnaissance Orbiter, Mars Reconnaissance Orbiter) if it were officially catalogued.

Note: The lack of authoritative references means that Mons Delisle should be considered a term of uncertain status within planetary science.
