Solar astrometry deals with the accurate measumerent of the solar diameter,
and in general with the measurement of the shape of the Sun. During the last
decades several techniques have been developed to monitor the radius and the
irradiance of the Sun: meridian transits, telescopes in drift-scan mode, solar
astrolabes, balloons, and satellites dedicated to the measurements of the solar
diameter, and space measurements of the total solar irradiance are now
performed to know the relationship radius-luminosity for the Sun in this
evolutionary stage of its life. The feedback of solar astrometry in climate
studies is of paramount importance. The status of art in the various fields of
research here adressed is outlined.
