Meaning and Definition
The scientific study of the shape, dimensions, and gravitational field of the Moon; lunar geodesy.
The branch of astrogeology or celestial geodesy specifically concerned with the precise measurement and mapping of the Moon's physical features and gravitational anomalies. This includes establishing coordinate systems and reference points for lunar mapping and exploration.

FAQ
Frequently Asked Questions
No. Selenology is the broader scientific study of the Moon (its geology, origin, etc.), while selenodesy is a specific subfield focused on measuring its geometric shape, dimensions, and gravitational field.
It is used almost exclusively by planetary scientists, astrogeologists, geodesists working on extraterrestrial bodies, and engineers in space agencies involved in lunar exploration and mapping.
Yes. The pattern is used for other celestial bodies: 'areodesy' for Mars, 'heliodesy' for the Sun, and 'planetary geodesy' as the general term.
It describes an extremely specialised scientific discipline. The average person, and even many scientists outside planetary geophysics, will never have a need to use or encounter this term.
The scientific study of the shape, dimensions, and gravitational field of the Moon.
Selenodesy is usually academic, scientific, technical in register.
Selenodesy: in British English it is pronounced /ˌsɛlɪˈnɒdɪsi/, and in American English it is pronounced /ˌsɛlɪˈnɑːdəsi/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of 'SELENE' (the Greek moon goddess) + 'DESY' (sounds like 'geodesy', the science of Earth's shape). So, 'selenodesy' is geodesy for the Moon.
Conceptual Metaphor
The Moon as a measurable, mappable body analogous to Earth.
