5819 Lauretta           Discovered 1989 Oct. 29 by S. J. Bus at Cerro Tololo.
Dante Lauretta (b. 1970), a professor at the University of Arizona, is known for his ground-breaking experimental work on the formation of iron-bearing sulfides in the solar nebula. He has also investigated the cosmochemical behavior of many elements such as mercury, boron and beryllium in meteorites.
