16765 Agnesi, provisional designation 1996 UA, is a stony asteroid from the middle region of the asteroid belt, about 4 kilometers in diameter. It was discovered on 16 October 1996, by Italian-American amateur astronomer Paul Comba at his private Prescott Observatory in the U.S. state of Arizona.[5]
The asteroid is a member of the Eunomia family, a large group of S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun at a distance of 2.3–2.9 AU once every 4 years and 3 months (1,555 days). Its orbit is tilted by 12 degrees to the plane of the ecliptic and shows an eccentricity of 0.11.[1] A photometric light-curve analysis at the Palomar Transient Factory Survey in 2013 has rendered a rotation period of 7.5458±0.0034 hours with a brightness amplitude of 0.31 in magnitude.[4] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 for the asteroid's surface, identical the to albedo of the family's namesake, 15 Eunomia.[3]
The minor planet was named in honour of Italian Maria Gaetana Agnesi (1718–1799), who was the first woman in the Western world to write a widely translated mathematics handbook and the first woman appointed to a professorship at a university in 1750.[2]
