1503 Kuopio, provisional designation 1938 XD, is a stony Eunomian

Turku Observatory in Southwest Finland.[13] The asteroid was named for the Finnish town of Kuopio.[2]

Orbit and classification

Kuopio is a member of the

502), a prominent family of stony S-type asteroid and the largest one in the intermediate main belt with more than 5,000 members.[3][4][14]: 23  It orbits the Sun at a distance of 2.3–2.9 AU once every 4 years and 3 months (1,553 days). Its orbit has an eccentricity of 0.10 and an inclination of 12° with respect to the ecliptic.[1]

The body's observation arc begins with its first identification as 1935 EF at Yerkes Observatory in March 1935, more than 3 years prior to its official discovery observation at Turku.[13]

Poles

In 2011 and 2013, a modeled lightcurve using data from the Uppsala Asteroid Photometric Catalogue (UAPC) and other sources was published. In both studies, the modeled lightcurve gave a concurring period 9.9586 hours. The 2013-publication also determined two

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

albedo between 0.223 and 0.399.[5][6][7]

The Collaborative Asteroid Lightcurve Link derives an albedo of 0.3243 and a diameter of 18.54 kilometers based on an absolute magnitude of 10.5.[3]
