Work

Abetti mainly worked in positional astronomy and made many observations of minor planets, comets, and star occultations. In 1874 he was part of an expedition led by Pietro Tacchini to observe a transit of Venus with a spectroscope. Later he became director of the Osservatorio Astrofisico di Arcetri and a professor at the University of Florence. He refurbished the observatory at Arcetri by installing a new telescope.
