He found the first object in the asteroid belt—Ceres, now classified as a dwarf planet—filling a gap astronomers had long suspected lay between Mars and Jupiter.

Biography

About

Giuseppe Piazzi was born on 16 July 1746, an Italian Catholic priest in the Theatine order who also worked as a mathematician and astronomer. He established an observatory at Palermo, a facility that still operates today as the Osservatorio Astronomico di Palermo – Giuseppe S. Vaiana. On a January night in 1801, while mapping stars, he spotted a moving point of light that turned out to be Ceres—the first dwarf planet ever identified, though it would take two centuries for that classification to settle. He died on 22 July 1826, having opened a door to an entire population of small worlds.
