2173 Maresjev, provisional designation Template:Mp, is a dark background asteroid from the outer regions of the asteroid belt, approximately Script error: No such module "convert". in diameter. It was discovered on 22 August 1974, by Soviet–Ukrainian astronomer Lyudmila Zhuravleva at the Crimean Astrophysical Observatory in Nauchnij, on the Crimean peninsula.[1] It was named for Soviet war veteran Alexey Maresyev. The assumed C-type asteroid has a tentative rotation period of 11.6 hours.[2]
Orbit and classification
Maresjev is a non-family asteroid from the main belt's background population.[3] It orbits the Sun in the outer asteroid belt at a distance of 2.8–3.5 AU once every 5 years and 7 months (2,031 days; semi-major axis of 3.14 AU). Its orbit has an eccentricity of 0.11 and an inclination of 14° with respect to the ecliptic.[4]
The body's observation arc begins with its first observations as Template:Mp at Heidelberg Observatory in March 1933, or 41 years prior to its official discovery observation at Nauchnij.[1]
Physical characteristics
Maresjev is an assumed carbonaceous C-type asteroid.[2]
Rotation period
In September 2007, a fragmentary rotational lightcurve of Maresjev was obtained from photometric observations by astronomers at the Oakley Observatory in the United States. Lightcurve analysis gave a rotation period of 11.6 hours with a brightness amplitude of 0.42 magnitude (U=1Script error: No such module "Check for unknown parameters".).[5] As of 2018, no secure period has been obtained.[2]
Diameter and albedo
According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Maresjev measures between 20.61 and 29.265 kilometers in diameter and its surface has an albedo between 0.0568 and 0.11.[6][7][8][9]
The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.0580 and calculates a diameter of 28.96 kilometers based on an absolute magnitude of 11.4.[2]
Naming
This minor planet was named after Alexey Maresyev (1916–2001), a Soviet war veteran and fighter ace. His story served as a basis for the novel Story about a True Man (also translated as Story of a Real Man) by Boris Polevoy, which became a popular Russian book that was eventually made into an opera. It was first published in English in 1952, and was reprinted in 1970.[1][10]
The official naming citation was published by the Minor Planet Center on 1 April 1980 (M.P.C. 5285Script error: No such module "Check for unknown parameters".).[11]
