It was discovered on 27 August 2005, by astronomers Franco Mallia and Alain Maury at the Campo Catino Austral Observatory (CAO), San Pedro de Atacama, Chile, a robotic station of the Italian Campo Catino Astronomical Observatory. The asteroid was named for Italian composer Ennio Morricone.[2] Orbit and classificationMorricone is a non-family from the main belt's background population.[3] It orbits the Sun in the central asteroid belt at a distance of 2.1–3.0 AU once every 4 years and 1 month (1,494 days; semi-major axis of 2.56 AU). Its orbit has an eccentricity of 0.18 and an inclination of 15° with respect to the ecliptic.The body's observation arc begins with its observation by AMOS at Haleakala Observatory in August 2001, or four years prior to its official discovery observation by CAO at San Pedro de Atacama in Chile.[2] Physical characteristicsThe asteroid's spectral type is unknown. Diameter and albedoMorricone has not been observed by any of the space-based surveys such as the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite or the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer. Based on a generic magnitude-to-diameter conversion, the asteroid measures 2.3 and 4.2 kilometers in diameter based on an absolute magnitude of 15.6 and a geometric albedo of 0.06 and 0.20, which roughly correspond to a body of carbonaceous and stony composition, respectively (both types are common in the central asteroid belt).[2][5]Rotation periodAs of 2018, no rotational lightcurve of Morricone has been obtained from photometric observations. The body's rotation period, shape and poles remain unknown.[17] NamingThis minor planet was named after Italian composer Ennio Morricone (born 1928), who has written over 500 scores for cinema and television including several famous Spaghetti Western. The official naming citation was published by the Minor Planet Center on 1 June 2007 ({{small|M.P.C. 59925}}).[18] References1. ^1 2 3 4 5 {{cite web |title = 152188 Morricone (2005 QP51) |work = Minor Planet Center |url = https://www.minorplanetcenter.net/db_search/show_object?object_id=152188 |accessdate = 16 January 2018}} [1][2][3][4][5]2. ^1 {{cite web |title = MPC/MPO/MPS Archive |work = Minor Planet Center |url = https://www.minorplanetcenter.net/iau/ECS/MPCArchive/MPCArchive_TBL.html |accessdate = 16 January 2018}} 3. ^1 2 {{cite web |title = Small Bodies Data Ferret |work = Nesvorny HCM Asteroid Families V3.0 |url = https://sbntools.psi.edu/ferret/PropertySearch/familyForm.action |accessdate = 16 January 2018}} 4. ^1 2 3 {{cite web |title = Asteroid Size Estimator |publisher = CNEOS NASA/JPL |url = https://cneos.jpl.nasa.gov/tools/ast_size_est.html |accessdate = 16 January 2018}} 5. ^1 {{cite web |title = LCDB Data for (152188) Morricone |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=152188%7CMorricone |accessdate = 16 January 2018}} }} External links
