It was discovered on 9 September 1934, by Dutch astronomer Hendrik van Gent at the Union Observatory in Johannesburg, South Africa.[33] The asteroid was named for the Dutch province of Zeeland.[2] Orbit and classificationZeelandia belongs to the Koronis family ({{small|605}}),[3][4] a very large asteroid family of 6,000 known members with stony composition and nearly co-planar ecliptical orbits.[37]It orbits the Sun in the outer main-belt at a distance of 2.7–3.0 AU once every 4 years and 10 months (1,757 days; semi-major axis of 2.85 AU). Its orbit has an eccentricity of 0.06 and an inclination of 3° with respect to the ecliptic. In October 1905, a first precovery was taken at the Lowell Observatory in Arizona. Its first identification as {{mp|A906 YO}} was made at Taunton Observatory ({{small|803}}) in December 1906. The body's observation arc begins with its official discovery observation at Johannesburg in September 1934.[33] Physical characteristicsZeelandia has been characterized as a stony S-type asteroid in both the Tholen and SMASS classification.Rotation periodIn March 2004, a rotational lightcurve of Zeelandia was obtained from photometric observations by a collaboration of American astronomers. Lightcurve analysis gave a well-defined rotation period of 15.602 hours with a brightness variation of 0.61 magnitude ({{small|U=3}}).[12] The result was confirmed by photometrists Pierre Antonini, Federico Manzini, Julian Oey and Frederick Pilcher, as well as Hiromi and Hiroko Hamanowa, who measured a similar period of 15.624 with an amplitude of 0.50 magnitude in April 2005 ({{small|U=3}}).[13] 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, Zeelandia measures between 19.18 and 23.63 kilometers in diameter and its surface has an albedo between 0.153 and 0.273.[6][8][9][10][11] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.2183 and a diameter of 20.99 kilometers based on an absolute magnitude of 10.66.[3][8] NamingThis minor planet was named for the Dutch province of Zeeland. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 ({{small|H 121}}).[2] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (1336) Zeelandia |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 109 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_1337 |chapter = (1336) Zeelandia }} [1][2][3][4][5][6][7][8][9][10][11][12][13]2. ^1 2 {{cite web |title = 1336 Zeelandia (1934 RW) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=1336 |accessdate = 28 November 2017}} 3. ^1 2 {{cite web |title = Asteroids and comets rotation curves – (1336) Zeelandia |last = Behrend |first = Raoul |publisher = Geneva Observatory |url = http://obswww.unige.ch/~behrend/page4cou.html#001336 |accessdate = 28 November 2017}} 4. ^1 2 3 {{cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = T. |last2 = Grav |first3 = A.
