2080 Jihlava, provisional designation1976 DG, is a stony Floraasteroid from the inner regions of theasteroid belt, approximately 6 kilometers in diameter. The asteroid was discovered on 27 February 1976, by Swiss astronomerPaul Wild atZimmerwald Observatory near Bern, Switzerland.[7] It was named after the Czech city ofJihlava.[2]
Jihlava is a member of theFlora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in theinner main-belt at a distance of 2.0–2.3 AU once every 3 years and 3 months (1,173 days). Its orbit has aneccentricity of 0.06 and aninclination of 4° with respect to theecliptic.[1]
In 1955, the asteroid was first identified as1955 SH1 and1955 SH2 atGoethe Link Observatory andHeidelberg Observatory, respectively, and thereby extending the body'sobservation arc by 21 years prior to its official discovery observation at Zimmerwald.[7]
The asteroid has been characterized as a commonS-type asteroid.[3]
The best rated rotationallightcurve ofJihlava gaverotation period of 2.70876 hours with a brightness variation of 0.15magnitude (U=3).[5]
According to the survey carried out by NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Jihlava measures 5.765 kilometers in diameter and its surface has an outstandingly highalbedo of 0.633,[4] while theCollaborative Asteroid Lightcurve Link assumes an albedo of 0.24 — derived from8 Flora, the family's largest member and namesake – and calculates a diameter of 7.14 kilometers with anabsolute magnitude of 12.9.[3]
Thisminor planet was named after the city ofJihlava in the Czech Republic. The Moravian town, by the river of the same name was founded in the 11th century and is the country's oldest mining town with a community that prospered from rich silver deposits. The municipal and mining laws of Jihlava were to become a model for analogous regulations all over the world.
The name was proposed by astronomerIvo Baueršíma, a geodesist at theUniversity of Berne and co-discoverer of the minor planet9711 Želetava, in honor of his native town.[2] The officialnaming citation was published by theMinor Planet Center on 1 July 1979 (M.P.C. 4786).[8]
