1068 Nofretete(/nɒfrəˈtiːtə/[a]), provisional designation1926 RK,is a stonyasteroidfrom thebackground populationin the outerasteroid belt,approximately 23 kilometers in diameter. It was discovered on 13 September 1926, by Belgian astronomerEugène Delporteat theRoyal Observatory of Belgiumin Uccle.[11]The asteroid was named after the Ancient Egyptian QueenNefertitiby its German name "Nofretete".[2]The near-Earth asteroid3199 Nefertitiis also named after her.

Orbit and classification

edit

Nofreteteis a non-familyasteroid from the main belt'sbackground population.[4]It orbits the Sun in theouterasteroid belt at a distance of 2.6–3.2AUonce every 4 years and 12 months (1,810 days;semi-major axisof 2.91 AU). Its orbit has aneccentricityof 0.10 and aninclinationof 5°with respect to theecliptic.[1]The body'sobservation arcbegins at Uccle in September 1926, three nights after its official discovery observation.[11]

Physical characteristics

edit

Nofretetehas been characterized as a stonyS-type asteroidby American astronomerRichard Binzel.[9]

Rotation period

edit

In May 1984, a rotationallightcurveofNofretetewas obtained from photometric observations by Richard Binzel which gave arotation periodof 6.15 hours with a low brightness amplitude of 0.04magnitude,indicative for a nearly spheroidal shape (U=2).[9]

Diameter and albedo

edit

According to the surveys carried out by the JapaneseAkari satelliteand theNEOWISEmission of NASA'sWide-field Infrared Survey Explorer,Nofretetemeasures between 21.346 and 26.73 kilometers in diameter and its surface has analbedobetween 0.104 and 0.1832.[5][6][7][8]

TheCollaborative Asteroid Lightcurve Linkassumes a standard albedo for stony asteroids of 0.20 and derives a diameter of 22.03 kilometers based on anabsolute magnitudeof 10.65.[3]

Naming

edit

Thisminor planetwas named by German astronomerGustav Strackeafter the Ancient Egyptian QueenNefertiti(c.1370 – c.1330 BC) by its common German name "Nofretete".[a]She was the wife of pharaohAkhenaten(a.k.a. Echnaton or Amenhotep IV), after whom the asteroid4847 Amenhotepis named. The official naming citation was mentioned inThe Names of the Minor PlanetsbyPaul Hergetin 1955 (H 101). The near-Earth asteroid3199 Nefertiti,discovered by American astronomersCarolynandEugene Shoemakerat Palomar, was also named after her.[2]
