Tergeste (

Heidelberg Observatory in southern Germany.[14] It was named after the Italian city of Trieste.[3]

Classification and orbit

Tergeste orbits the Sun in the outer main-belt at a distance of 2.8–3.3 AU once every 5 years and 3 months (1,915 days). Its orbit has an eccentricity of 0.08 and an inclination of 13° with respect to the ecliptic.[1] The body's observation arc begins with its first used observation at Koenigsberg Observatory, 2 days after its official discovery at Heidelberg.[14]

Physical characteristics

Tergeste is a stony

SMASS taxonomy.[15]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

albedo between 0.155 and 0.191.[5][6][7][8][9] The Collaborative Asteroid Lightcurve Link agrees with the revised WISE results and takes an albedo of 0.1914, an absolute magnitude of 7.96 and a diameter of 77.1 kilometers.[4][6]

Lightcurves

In July 2005, a rotational

U=2+),[11] superseding a period of 15±5 hours from the 1980s (U=n/a).[10]

In January 2013, another lightcurve was obtained during a photometric survey by predominantly Polish and Japanese observatories. It gave a similar period of 16.105±0.001 hours with an amplitude of 0.30 magnitude (

U=n/a).[12]

Naming

This minor planet is named for the northeastern Italian city of Trieste (also known by its pre-Roman name "Tergeste"). It is the birthplace of the discoverer,[3] who also worked there as director of the Trieste Observatory for many years.
