7675 Gorizia
7675 Gorizia, provisional designation, is a background asteroid from the inner regions of the asteroid belt, approximately 3 kilometers in diameter. It was discovered on 23 November 1995, by the staff at Farra d'Isonzo Observatory in northeastern Italy. It is named for the Italian town of Gorizia.
Orbit and classification
Gorizia orbits the Sun in the inner main-belt at a distance of 2.2–2.6 AU once every 3 years and 9 months. Its orbit has an eccentricity of 0.09 and an inclination of 5° with respect to the ecliptic. In 1976, it was first identified as at the Japanese Kiso Observatory, extending the body's observation arc by 19 years prior to its official discovery observation.Physical characteristics
As of 2017, Gorizias effective size and composition, as well as its rotation period and shape remain unknown. No estimates about Gorizias diameter and albedo have been published by any of the space-based surveys such as the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, or NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission. It has an absolute magnitude of 14.4.Based on a generic magnitude-to-diameter conversion, Gorizia measures between 3 and 7 kilometers for an albedo in the range of 0.05 to 0.25. Since asteroids in the inner main-belt are often of a silicaceous rather than of a carbonaceous composition, with higher albedos, typically around 0.20, Gorizias diameter might be on the lower end of NASA's published conversion table, as the higher the body's reflectivity, the smaller its diameter, for a given absolute magnitude.
