2034 Bernoulli (/bərˈnuːli/), provisional designation1973 EE, is a stonyasteroid from the inner regions of theasteroid belt, approximately 9 kilometers in diameter.
The asteroid was discovered on 5 March 1973, by Swiss astronomerPaul Wild atZimmerwald Observatory near Bern, Switzerland, and named for the members of theBernoulli family.[2][7]
Bernoulli orbits the Sun in theinner main-belt at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,230 days). Its orbit has aneccentricity of 0.18 and aninclination of 9° with respect to theecliptic.[1] The first usedprecovery was taken atPalomar Observatory in 1951, extending the asteroid'sobservation arc by 22 years prior to its official discovery, while the first unused observation was made ten years earlier atUccle Observatory in 1941.[7]
Bernoulli is an assumed, common, stonyS-type asteroid.[3]
A rotationallightcurve ofBernoulli was obtained from photometric observations by Michael Alkema at the U.S. Elephant Head Observatory (G35), Arizona, in December 2012. Lightcurve analysis gave arotation period of6.248 hours with a brightness variation of 0.21magnitude (U=2+).[6]
According to the survey carried out by theNEOWISE mission of NASA's space-basedWide-field Infrared Survey Explorer,Bernoulli measures 7.8 and 8.5 kilometers in diameter and its surface has analbedo of 0.17 and 0.22, respectively,[4][5] while theCollaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 9.4 kilometers with anabsolute magnitude of 12.5.[3]
Thisminor planet was named in honour of theBernoulli family, a dynasty of mathematicians from the city of Basel, Switzerland. In particular,Jacob Bernoulli (1654–1705), founder of the calculus of variations,Daniel Bernoulli (1700–1782), co-founder of hydrodynamics, andJohann Bernoulli (1667–1748), contributor to integral calculus and the teacher of Leonhard Euler, after whom the minor planet2002 Euler is named.[2]
The lunar craterBernoulli also honors the Swiss dynasty.[2] The official naming citation was published by theMinor Planet Center on 1 June 1980 (M.P.C. 5359).[8]
