IPA: /æˈstrɒmətri/
KK: /æˈstrɒmətri/
The scientific study that involves measuring the positions and movements of stars and other celestial objects.
Astrometry is essential for understanding the dynamics of our solar system.
Astrometry is formed from "astro-" (from Greek "astron", meaning star) and "metria" (from Greek "metron", meaning measure). The word refers to the measurement of the positions and movements of stars and other celestial bodies.
Think of 'stars' ('astro-') being 'measured' ('metria') — that's what astrometry is all about.
