It was discovered on 8 February 1878, by Austrian astronomer Johann Palisa at the Austrian Naval Observatory in Pola, in what is now Croatia.[1] The S-type asteroid has a rotation period of 11.77 hours.[20] It was named for the Istrian Peninsula.[2] Orbit and classificationIstria is a non-family asteroid from the main belt's background population.[5][6] It orbits the Sun in the central main-belt at a distance of 1.8–3.8 AU once every 4 years and 8 months (1,703 days; semi-major axis of 2.79 AU). Its orbit has an eccentricity of 0.35 and an inclination of 26° with respect to the ecliptic.Physical characteristicsIstria has been characterized as a common, stony S-type asteroid in both the Tholen and SMASS classification.Rotation periodIn August 1979, a rotational lightcurve of Istria was obtained from photometric observations by American astronomer Alain Harris. Lightcurve analysis gave a well-defined rotation period of 11.77 hours with a brightness amplitude of 0.31 magnitude ({{small|U=3}}).[13] Observations by French amateur astronomer Laurent Bernasconi gave a similar period of 11.6 hours ({{small|U=2}}).[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, Istria measures between 30.779 and 35.43 kilometers in diameter and its surface has an albedo between 0.1890 and 0.2582.[8][9][10][11] NamingThis minor planet was named after the Istrian Peninsula in the Adriatic Sea, where the city of Pula (then Pola) with its discovering observatory is located. A the time the peninsula was part of the Austro-Hungarian Empire. The asteroid's name was given by Vice-Admiral Bernhard von Wüllerstorf-Urbair, who is known as the captain of the first Austrian circumnavigatory adventure with the sail frigate SMS Novara.[2] The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 ({{small|H 183}}).[2] References1. ^1 2 3 4 {{cite book |title = Dictionary of Minor Planet Names – (183) Istria |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 31 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_184 |chapter = (183) Istria }} [1][2][3][4][5][6][7][8][9][10][11][12][13]2. ^1 2 3 {{cite web |title = 183 Istria |work = Minor Planet Center |url = https://www.minorplanetcenter.net/db_search/show_object?object_id=183 |accessdate = 30 May 2018}} 3. ^1 2 {{cite web |title = Asteroids and comets rotation curves – (183) Istria |last = Behrend |first = Raoul |publisher = Geneva Observatory |url = http://obswww.unige.ch/~behrend/page1cou.html#000183 |accessdate = 30 May 2018}} 4. ^1 2 3 {{cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = T. |last2 = Grav |first3 = A.
