Asteroid 2542, Calpurnia, was discovered on February 11, 1980 by Edward "Ted" Bowell at the Anderson Mesa station of Lowell Observatory in Flagstaff, Arizona. It has a period of 5 years, 204 days and is about 20 miles in diameter.
It was named after the wife of Julius Caesar, who bore him no offspring.
Asteroid Calpurnia, astrologically, does seem to have the meaning of producing nothing.
