Astrometry is the science of mapping the positions of the stars, galaxies, and quasars, and recording the motions of the planet. It may be one of the oldest fields of astronomy and was studied by astronomers such as Galileo, Kepler, and Newton.
We use Astrometry today as an important way to keep time by relating atomic time to our Earth's rotation.
