 "Astrometry
is the branch of
astronomy that relates to precise measurements and
explanations of the positions and movements of
stars and other celestial bodies. Although once
thought of as an esoteric field with little useful
application for the future, the information obtained by
astrometric measurements is now very important in
contemporary research into the
kinematics and physical origin of our
Solar System and our
Galaxy, the
Milky Way."
