It was discovered on 5 February 1929, by astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in Germany.[22] The asteroid was named for the fruit-bearing tree Cydonia (quince).[2] The S-type asteroid has a relatively short rotation period of 2.7 hours.[3] Orbit and classificationCydonia is a member of the Eunomia family ({{small|502}}),[3][4] a prominent family of stony asteroids and the largest one in the intermediate main belt with more than 5,000 members.[27] It orbits the Sun in the central asteroid belt at a distance of 2.3–2.9 AU once every 4 years and 2 months (1,528 days; semi-major axis 2.60 AU). Its orbit has an eccentricity of 0.13 and an inclination of 13° with respect to the ecliptic. The body's observation arc begins with its first and official discovery observation at Heidelberg in February 1929.[22]Physical characteristicsIn the SMASS classification, Cydonia is a stony S-type asteroid,[3] in-line with the Eunomia family's overall spectral type.[27]{{rp|23}} Rotation periodIn December 2015, a rotational lightcurve of Cydonia was obtained from photometric observations by astronomers at the Etscorn Observatory ({{small|719}}) in New Mexico, United States. Lightcurve analysis gave a well-defined rotation period of 2.679 hours with a brightness variation of 0.28 magnitude ({{small|U=3}}).[11] In April 2017, Spanish astronomers at Puçol Observatory ({{small|J42}}) and other stations of the APTOG-network measured a similar period of 2.6700 hours and an amplitude of 0.10 magnitude ({{small|U=2+}}).[10] Diameter and albedoAccording to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Cydonia measures between 12.140 and 12.95 kilometers in diameter and its surface has an albedo between 0.1719 and 0.241.[6][7][8] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 – derived from 15 Eunomia, the family's parent body and namesake – and calculates a diameter of 13.26 kilometers based on an absolute magnitude of 11.7.[3] NamingThis minor planet was named after the genus Cydonia in the Rosaceae family, with the fruit-bearing quince tree as its only member. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 ({{small|H 104}}).[2] Reinmuth's flowersDue to his many discoveries, Karl Reinmuth submitted a large list of 66 newly named asteroids in the early 1930s. The list covered his discoveries with numbers between {{MoMP|1009|(1009)}} and {{MoMP|1200|(1200)}}. This list also contained a sequence of 28 asteroids, starting with 1054 Forsytia, that were all named after plants, in particular flowering plants (also see list of minor planets named after animals and plants).[40] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (1106) Cydonia |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 94 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_1107 |chapter = (1106) Cydonia }} [1][2][3][4][5][6][7][8][9][10][11][12]2. ^1 {{cite book |title = Dictionary of Minor Planet Names – (1054) Forsytia |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 90 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_1055 |chapter = (1054) Forsytia }} 3. ^1 2 {{cite web |title = 1106 Cydonia (1929 CW) |work = Minor Planet Center |url = https://www.minorplanetcenter.net/db_search/show_object?object_id=1106 |accessdate = 28 February 2018}} 4. ^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 = 28 February 2018}} 5. ^1 2 {{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 {{cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = T. |last2 = Grav |first3 = A.
