It was discovered on 24 September 1960, by Dutch astronomer couple Ingrid and Cornelis van Houten at Leiden, on photographic plates taken by Dutch–American astronomer Tom Gehrels at the U.S Palomar Observatory, California.[14] It was later named after the Egyptian pharaoh Amenemhět III.[2] Orbit and classificationAmenemhêt orbits the Sun in the central main-belt at a distance of 2.2–3.3 AU once every 4 years and 6 months (1,633 days). Its orbit has an eccentricity of 0.20 and an inclination of 15° with respect to the ecliptic. Its observation arc already begins in 1955, due to precoveries taken at the U.S. Goethe Link Observatory in Indiana.[14]Physical characteristicsIn the SMASS taxonomic scheme, Amenemhêt is classified as a common stony asteroid with a S-type spectrum. It has also been characterized as a S-type by Pan-STARRS{{'}} large-scale survey.[10] LightcurveA rotational lightcurve was obtained through photometric observations at the Serbian Belgrade Astronomical Observatory in May 2008. Lightcurve analysis showed a period of {{val|3.390 }} hours with a brightness amplitude of 0.18 magnitude ({{small|U=3-}}),[6] superseding a previous lightcurve from two South-American observatories ({{small|U=1}}).[5] Diameter and albedoThe Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 9.4 kilometers with an absolute magnitude of 12.5.[4] Palomar–Leiden surveyThe survey designation "P-L" stands for Palomar–Leiden, named after Palomar Observatory and Leiden Observatory, which collaborated on the fruitful Palomar–Leiden survey in the 1960s. Gehrels used Palomar's Samuel Oschin telescope – also known as the 48-inch Schmidt Telescope – and shipped the photographic plates to Ingrid and Cornelis van Houten at Leiden where astrometry was carried out. The trio are credited with the discovery of several thousand minor planets.[22] NamingThis minor planet was named after the Egyptian pharaoh Amenemhět III (1844–1797 B.C.), who built the Great Canal (Mer-Wer) and brought prosperity to the Faiyum Oasis by linking it with the Nile. The area then became a breadbasket for the country. At the Hawara site in Faiyum, he built a mortuary temple, which the Greek historian Herodotus referred to as "labyrinth". Amenemhět's father was the pharaoh Sesostris III (also see the minor planets 4414 Sesostris and 3092 Herodotus).[2] The official naming citation was published on 1 September 1993 ({{small|M.P.C. 22505}}).[24] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (5010) Amenemhět |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 431 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_4881 |chapter = (5010) Amenemhět }} [1][2][3][4][5][6][7][8]2. ^1 2 {{cite web |title = 5010 Amenemhet (4594 P-L) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=5010 |accessdate = 16 April 2016}} 3. ^1 {{cite web |title = Minor Planet Discoverers |work = Minor Planet Center |url = http://www.minorplanetcenter.net/iau/lists/MPDiscsNum.html |date = 24 April 2016 |accessdate = 17 May 2016}} 4. ^1 {{cite web |title = MPC/MPO/MPS Archive |work = Minor Planet Center |url = http://www.minorplanetcenter.net/iau/ECS/MPCArchive/MPCArchive_TBL.html |accessdate = 17 May 2016}} 5. ^1 2 3 4 5 {{cite web |title = LCDB Data for (5010) Amenemhet |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=5010%7CAmenemhet |accessdate = 16 April 2016}} 6. ^1 2 {{cite journal |display-authors = 6 |first1 = C.
