882 Swetlana (prov. designation: {{mp|A917 PB}} or {{mp|1917 CM}}) is a dark background asteroid from the outer region of the asteroid belt. It was discovered on 15 August 1917, by Russian astronomer Grigory Neujmin at the Simeiz Observatory on the Crimean peninsula. The X-type asteroid has a longer-than average rotation period of 29.9 hours and measures approximately {{convert|42|km|mi|abbr=off|sigfig=2|sp=us}} in diameter. The origin of the asteroid's name remains unknown.
Orbit and classification
Swetlana is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements. It orbits the Sun in the outer asteroid belt at a distance of 2.3–4.0 AU once every 5 years and 6 months (2,016 days; semi-major axis of 3.12 AU). Its orbit has an eccentricity of 0.27 and an inclination of 6° with respect to the ecliptic. The body's observation arc begins on 18 August 1917, with its independent discovery at Heidelberg Observatory by Max Wolf, just three nights after its official discovery observation by Grigory Neujmin at Simeiz.
Naming
This minor planet is named after a Feminine Russian first name. Any reference of this name to a person or occurrence is unknown.
= Unknown meaning =
Among the many thousands of named minor planets, Swetlana is one of 120 asteroids, for which no official naming citation has been published. All of these low-numbered asteroids have numbers between {{mp|{{MoMP|164|164 Eva}}}} and {{mp|{{MoMP|1514|1514 Ricouxa}}}} and were discovered between 1876 and the 1930s, predominantly by astronomers Auguste Charlois, Johann Palisa, Max Wolf and Karl Reinmuth.
Physical characteristics
In both the Tholen- and SMASS-like taxonomy of the Small Solar System Objects Spectroscopic Survey (S3OS2), Swetlana is an X-type asteroid.
= Rotation period =
In September 2017, a rotational lightcurve of Swetlana was obtained from photometric observations by Thomas A. Polakis at the Command Module Observatory {{Obscode|V02}} in Arizona. Lightcurve analysis gave a well-defined rotation period of {{val|29.867|0.009}} hours with a brightness variation of {{val|0.38|0.02}} magnitude ({{small|U=3}}). The result supersedes an observations by Italian amateur astronomers Roberto Crippa and Federico Manzini at the Sozzago Astronomical Station {{Obscode|A12}} from September 2006, which tentatively determined a period of more than 20 hours and an amplitude of {{val|0.17|0.05}} magnitude ({{small|U=2−}}).
= Diameter and albedo =
According to the surveys carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer (WISE), the Infrared Astronomical Satellite IRAS, and the Japanese Akari satellite, Swetlana measures ({{val|42.440|0.313}}), ({{val|43.55|2.2}}) and ({{val|44.94|0.50}}) kilometers in diameter and its surface has an albedo of ({{val|0.062|0.011}}), ({{val|0.0588|0.006}}) and ({{val|0.056|0.002}}), respectively. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0491 and a diameter of 43.47 kilometers based on an absolute magnitude of 10.7. Alternative measurements published by the WISE team include mean-diameters of ({{val|39.014|0.412|u=km}}) and ({{val|39.346|0.766|u=km}}) with corresponding albedos of ({{val|0.0733|0.0177}}) and ({{val|0.072|0.012}}).
