He became (1781) professor of mathematics at the Univ. of Palermo, supervised construction of a government observatory (opened 1791) at Palermo, and was its first director. He also established a government observatory at Naples (1817). He was the first to discover (Jan. 1, 1801) an asteroid asteroid, planetoid, or minor planet, small body orbiting the sun. More than 10,000 asteroids have orbits sufficiently well known to have been cataloged and named; thousands more exist.
