    183 Istria is a stony background asteroid from the central regions of the asteroid belt, approximately 33 kilometers (21 miles) in diameter. 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. [13] It was named for the Istrian Peninsula. [3]

    Orbit and classification

    Istria 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. [4]

    Physical characteristics

    Istria has been characterized as a common, stony S-type asteroid in both the Tholen and SMASS classification. [4]

    Rotation period

    In 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 ( U=3 ). [12] Observations by French amateur astronomer Laurent Bernasconi gave a similar period of 11.6 hours ( U=2 ). [11]

    Diameter and albedo

    According 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. [7] [8] [9] [10]

    Naming

    This 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. [3] The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 ( H 183 ). [3]
