Sicoli, Piero
He works at the Osservatorio Astronomico Sormano (Italy) where he has discovered about fifty new asteroids and identified several hundred, including some PHA (potentially hazardous asteroids). Combining his passion for celestial mechanics and historical comets, he has tried to calculate some of their orbits. In 1999, asteroid (7866) Sicoli, discovered at Lowell Observatory in Arizona, was named after him.
