It was discovered on 16 March 1936, by astronomer Louis Boyer at the Algiers Observatory in Algeria, North Africa.[30] The asteroid was named after the discoverer's nephew, Pierre.[2] Orbit and classificationPierre is a dynamical member of the Eunomia family ({{small|502}}),[3] a prominent family of stony asteroids and the largest one in the intermediate main belt with more than 5,000 members.[4] However, it is a non-family asteroid of the main belt's background population when applying the Hierarchical Clustering Method to its proper orbital elements.[4] As Pierre{{'}}s spectral type is also different from that of the Eunomia family (see below), it is possibly an interloper to the Eunomia family rather than a true member.{{citation needed|date=October 2017}} It orbits the Sun in the central main-belt at a distance of 2.1–3.1 AU once every 4 years and 3 months (1,538 days). Its orbit has an eccentricity of 0.20 and an inclination of 12° with respect to the ecliptic. The asteroid was first identified as {{mp|A917 UB}} at Simeiz Observatory in October 1917. The body's observation arc begins with its official discovery observation at Algiers in March 1936.[30] Physical characteristicsPierre has been characterized as a carbonaceous C-type asteroid by Pan-STARRS photometric survey.[20] In the Tholen classification, the asteroid's spectral type is ambiguous, closest to a dark D-type and somewhat similar to a generic X-type asteroid. Conversely, the Eunomia family consists of S-type asteroids.[39]{{rp|23}} Rotation periodIn August 1984, a first rotational lightcurve of Pierre was obtained from photometric observations with the ESO 1-metre telescope at the La Silla Observatory in Chile. Lightcurve analysis gave a rotation period of 18 hours with a brightness variation of 0.09 magnitude ({{small|U=2}}).[11] A poorly rated lightcurve by Pierre Antonini in Januar 2007, gave a period of 24 hours with an amplitude of 0.05 magnitude.[12] Diameter and albedoAccording to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Pierre measures between 26.16 and 28.94 kilometers in diameter and its surface has an albedo between 0.04 and 0.054.[6][8][9][10] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0519 and a diameter of 26.44 kilometers based on an absolute magnitude of 11.72.[3][8] NamingThis minor planet was named after Pierre, a nephew of the discoverer Louis Boyer. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 ({{small|H 126}}).[2] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (1392) Pierre |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 112 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_1393 |chapter = (1392) Pierre }} [1][2][3][4][5][6][7][8][9][10][11][12]2. ^1 2 {{cite web |title = 1392 Pierre (1936 FO) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=1392 |accessdate = 26 October 2017}} 3. ^1 2 {{cite web |title = Asteroids and comets rotation curves – (1392) Pierre |last = Behrend |first = Raoul |publisher = Geneva Observatory |url = http://obswww.unige.ch/~behrend/page4cou.html#001392 |accessdate = 26 October 2017}} 4. ^1 2 3 {{cite web |title = Small Bodies Data Ferret |work = Nesvorny HCM Asteroid Families V3.0 |url = https://sbntools.psi.edu/ferret/PropertySearch/familyForm.action |accessdate = 26 October 2017}} 5. ^1 {{Cite book |first1 = D. |last1 = Nesvorný |first2 = M. |last2 = Broz |first3 = V. |last3 = Carruba |date = December 2014 |title = Identification and Dynamical Properties of Asteroid Families |journal = Asteroids IV |pages = 297–321 |bibcode = 2015aste.book..297N |doi = 10.2458/azu_uapress_9780816532131-ch016 |arxiv = 1502.01628 |isbn = 9780816532131 }} 6. ^1 2 3 4 5 6 7 {{cite web |title = LCDB Data for (1392) Pierre |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=1392%7CPierre |accessdate = 26 October 2017}} 7. ^1 2 3 4 {{cite journal |display-authors = 6 |first1 = C.
