Шаблон:Short description Шаблон:Infobox planet

Vienna (minor planet designation: 397 Vienna) is a typical Main belt asteroid. It was discovered by French astronomer Auguste Charlois on 19 December 1894 in Nice, and was most likely named after the city of Vienna, Austria.[1] This object is orbiting the Sun at a distance of Шаблон:Val with an orbital eccentricity (ovalness) of 0.246 and a period of Шаблон:Cvt. The orbital plane is inclined at an angle of 12.85° to the ecliptic.[2]

Photometric observations from multiple sites during 2017 were combined to produce an irregular light curve showing a rotation period of Шаблон:Val with a luminosity amplitude of Шаблон:Val in magnitude. This result is consistent with previous measurements.[3] The Tholen spectral type of this object is S and the SMASSII spectral type is K. Although the 'S' class suggests a stony composition, the latter class is consistent with carbonaceous chondrite meteorites.[4] Infrared observations from NEOWISE indicate a diameter of Шаблон:Val.[2]
