3054 Strugatskia, provisional designation 1977 RE7, is a dark Themistian asteroid from the outer regions of the asteroid belt, approximately 27 kilometers (17 miles) in diameter. It was discovered on 11 September 1977, by Soviet–Russian astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory in Nauchnij, on the Crimean peninsula. The asteroid was named after the brothers Arkady and Boris Strugatsky, two Russian science fiction authors.
Orbit and classification
Strugatskia is a Themistian asteroid that belongs to the Themis family (602), a very large family of carbonaceous asteroids, named after 24 Themis. It orbits the Sun in the outer asteroid belt at a distance of 2.4–3.7 AU once every 5 years and 5 months (1,986 days; semi-major axis of 3.09 AU). Its orbit has an eccentricity of 0.21 and an inclination of 2° with respect to the ecliptic.
The asteroid was first observed as 1928 UC at Heidelberg Observatory in October 1928. The body's observation arc begins at Goethe Link Observatory in May 1959, more than 18 years prior to its official discovery observation at Nauchnij.
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Strugatskia measures 26.921 kilometers in diameter and its surface has an albedo of 0.056, typical for carbonaceous asteroids.
This minor planet was named after the brothers Arkady Strugatsky (1925–1991) and Boris Strugatsky (1933–2012), two Russian of science fiction writers who often worked in collaboration. The official naming citation was published by the Minor Planet Center on 2 July 1985 (M.P.C. 9771).
