3199 Nefertiti (/nɛfərˈtiːti/nef-ər-TEE-tee), provisional designation1982 RA, is a rare-typeasteroid, classified asnear-Earth object of theAmor group of asteroids, approximately 2.2 kilometers in diameter. It was discovered on 13 September 1982, by American astronomer coupleCarolyn andEugene Shoemaker atPalomar Observatory, California, United States.[3]
Nefertiti orbits the Sun at a distance of 1.1–2.0 AU once every 1 years and 12 months (722 days). Its orbit has aneccentricity of 0.28 and aninclination of 33° with respect to theecliptic.[1]
It has an Earthminimum orbital intersection distance of 0.2157 AU (32,300,000 km), or 84lunar distances. As noprecoveries were taken, and no prior identifications were made, the body'sobservation arc begins with its official discovery observation at Palomar in 1982.[3]
In theTholen andSMASS taxonomy,Nefertiti is a stonyS-type and transitional Sq-type, respectively. In addition, itsspectral type is also that of a bright and rareK andQ type, according toSpitzer andPanSTARRS.[10][11] TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.326 and a diameter of 2.18 kilometers with anabsolute magnitude of 15.14.[4]
Several rotationallightcurves ofNefertiti have been obtained from photometric observations. In descending order of quality,rotation periods were derived by Czech astronomerPetr Pravec in the 1990s (3.021 hours; Δ0.30 mag;U=3),[8] at the Italian Padova and Catania observatories in February 2003 (3.021 hours; Δ0.19 mag;U=3-),[9] by Polish astronomerWiesław Z. Wiśniewski in the 1980s (2.82 hours; Δ0.12 mag;U=2),[5] by Finnish physicistMikko Kaasalainen (3.020167 hours; Δmag n.a.;U=n.a.),[7] and by Harris at JPL/Caltech in the 1980s (3.01 hours; Δ0.1 mag;U=n.a.).[6]
Thisminor planet was named for the ancient Egyptian queenNefertiti (ca. 1370–1330 BC), mother-in-law of pharaohTutankhamun and Chief King's Wife ofAkhenaten of the18th dynasty. Nefertiti and her "heretic" husband are believed to be responsible for a religious revolution, creating a new monotheistic religion, in which they only worshiped the sun disc godAten.[2] Another minor planet,1068 Nofretete is also named for her, using a different spelling. The official naming citation was published by theMinor Planet Center on 27 December 1985 (M.P.C. 10311).[13]
