9945 Karinaxavier           Discovered 1990 May 21 by E. F. Helin at Palomar.
Karina Xavier (b. 1977) is a citizen of both Brazil and the U.S. but might have chosen to be born in Italy had she been asked; instead she obtained her doctorate in Italian Renaissance literature. A true citizen of the world, she speaks five languages fluently, often all at once, and has a passion for soccer.
