8209 Toscanelli           Discovered 1995 Feb. 28 by P. Sicoli and P. Ghezzi at Sormano.
Paolo dal Pozzo Toscanelli (1397-1482) was an Italian physician, astronomer, cosmographer and mathematician. Columbus may have used his map of the world on the 1492 voyage. Toscanelli was the first to plot observations of comets on star charts, thereby supplying considerably improved information about their sky positions.
