It was discovered on 1 January 1929, by German astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany.[31] The asteroid was named after the flowering plant Fragaria (strawberry).[2] Orbit and classificationFragaria belongs to the Eos family ({{small|606}}),[3][4] the largest asteroid family of the outer asteroid belt consisting of nearly 10,000 members.[35] It orbits the Sun in the outer asteroid belt at a distance of 2.7–3.3 AU once every 5 years and 3 months (1,908 days; semi-major axis of 3.01 AU). Its orbit has an eccentricity of 0.11 and an inclination of 11° with respect to the ecliptic.The asteroid was first observed as {{mp|1916 MA}} at Simeiz Observatory in June 1916. The body's observation arc begins at Heidelberg in December 1928, three weeks prior to its official discovery observation.[31] Physical characteristicsIn the Tholen classification, Fragaria has an ambiguous spectral type, closest to an S-type and somewhat similar to the darker and uncommon T-type asteroids (ST),[3] while polarimetric observations characterized it as an U/L-type asteroid.[21] The overall spectral type for members of the Eos family is that of a K-type.[35]{{rp|23}} Rotation periodIn the 1990s, a rotational lightcurve of Fragaria was obtained from photometric observations by French and Italian astronomers at ESO's La Silla Observatory using the ESO 1-metre telescope. Lightcurve analysis gave a fragmentary rotation period of 10.88 hours with a brightness amplitude of 0.12 magnitude ({{small|U=1}}).[12] As of 2018, no secure period has been obtained.[3] 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, Fragaria measures between 27.92 and 38.41 kilometers in diameter and its surface has an albedo between 0.1017 and 0.166.[6][7][9][10][11] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1086 and a diameter of 36.95 kilometers based on an absolute magnitude of 10.19.[3] NamingThis minor planet was named after Fragaria, the genus of flowering plants in the rose family, commonly known as strawberries.[2] 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).[52] References1. ^1 2 3 4 {{cite book |title = Dictionary of Minor Planet Names – (1105) Fragaria |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_1106 |chapter = (1105) Fragaria }} [1][2][3][4][5][6][7][8][9][10][11][12][13]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 = 1105 Fragaria (1929 AB) |work = Minor Planet Center |url = https://www.minorplanetcenter.net/db_search/show_object?object_id=1105 |accessdate = 28 February 2018}} 4. ^1 2 3 {{cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = A.
