'''4082 Swann''', provisional designation {{mp|1984 SW|3}}, is a carbonaceous [[asteroid]] from the inner regions of the [[asteroid belt]], approximately 10 kilometers in diameter. It was discovered by American astronomer [[Carolyn Shoemaker]] at [[Palomar Observatory]] on 27 September 1984.<ref name="MPC-Swann" />
'''4082 Swann''' ({{mp|1984 SW|3}}) is a [[Asteroid belt|main-belt]] [[asteroid]] discovered on September 27, 1984 by [[C. S. Shoemaker]] at [[Palomar Observatory|Palomar]],<ref name="jpldata" /> and is named after her granddaughter, Carri Susan Swann. The rotational period is 4.0 hours. It has been examined spectroscopically, and appears to have a Class B asteroidal spectrum. Given the distance, magnitude and spectral type, it probably has an [[albedo]] in the range of 20 to 30, yielding a diameter in the range of 25 to 35 kilometers.

It orbits the Sun at a distance of 1.8–3.0&nbsp;[[Astronomical unit|AU]] once every 3 years and 8 months (1,349 days). Its orbit has an [[orbital eccentricity|eccentricity]] of 0.26 and an [[orbital inclination|inclination]] of 10[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" /> First identified as "1947&nbsp;UF" at the Finnish [[Turku Observatory]] in 1947, the asteroid's [[observation arc]] was extended by 37 years prior to its discovery.<ref name="MPC-Swann" />

The [[C-type asteroid|C-type]] asteroid is classified as a Ch-subtype in the [[SMASS classification|SMASS]] taxonomy. According to the surveys carried out by the Japanese [[Akari (satellite)|Akari]] satellite and NASA's [[Wide-field Infrared Survey Explorer]] with its subsequent [[NEOWISE]] mission, the asteroid measures 9.5 and 11.1 kilometers in diameter and its surface has an [[astronomical albedo|albedo]] of 0.029 and 0.101, respectively.<ref name="Masiero-2012" /><ref name="AKARI" /> The ''Collaborative Asteroid Lightcurve Link'', however, assumes a standard albedo for stony asteroids of 0.20 and derives a much smaller diameter of 5.85 kilometers, based on an absolute [[Magnitude (astronomy)|magnitude]] of 13.46.<ref name="lcdb" />

In July 2006, a rotational [[light-curve]] for this asteroid was obtained from photometric observations by Petr Pravec at the [[Ondřejov Observatory]] in the Czech Republic. It gave a [[rotation period]] of {{val|4.03632|0.00009}} hours with a brightness variation of 0.67 magnitude ({{small|[[LCDB quality code|U=3]]}}).{{efn|name=Pravec-2006-web}} A second light-curve obtained by Jean-Gabriel Bosch in September 2006, gave a period of {{val|4.1|0.1}} hours and an amplitude of 0.35 magnitude ({{small|[[LCDB quality code|U=2]]}}).<ref name="geneva-obs" />

The minor planet was named after American geologist Gordon A. Swann (b.&thinsp;1931).

4082 Swann, provisional designation 1984 SW3, is a carbonaceous asteroid from the inner regions of the asteroid belt, approximately 10 kilometers in diameter. It was discovered by American astronomer Carolyn Shoemaker at Palomar Observatory on 27 September 1984.[9]

It orbits the Sun at a distance of 1.8–3.0 AU once every 3 years and 8 months (1,349 days). Its orbit has an eccentricity of 0.26 and an inclination of 10° with respect to the ecliptic.[1] First identified as "1947 UF" at the Finnish Turku Observatory in 1947, the asteroid's observation arc was extended by 37 years prior to its discovery.[9]

The C-type asteroid is classified as a Ch-subtype in the SMASS taxonomy. According to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures 9.5 and 11.1 kilometers in diameter and its surface has an albedo of 0.029 and 0.101, respectively.[4][5] The Collaborative Asteroid Lightcurve Link, however, assumes a standard albedo for stony asteroids of 0.20 and derives a much smaller diameter of 5.85 kilometers, based on an absolute magnitude of 13.46.[3]

In July 2006, a rotational light-curve for this asteroid was obtained from photometric observations by Petr Pravec at the Ondřejov Observatory in the Czech Republic. It gave a rotation period of 4.03632±0.00009 hours with a brightness variation of 0.67 magnitude (U=3).[a] A second light-curve obtained by Jean-Gabriel Bosch in September 2006, gave a period of 4.1±0.1 hours and an amplitude of 0.35 magnitude (U=2).[6]

The minor planet was named after American geologist Gordon A. Swann (b. 1931). He served as the principal investigator of the "Apollo Lunar Geologic Experiment" conducted at the lunar landing sites of Apollo 14 and Apollo 15.[2] Naming citation was published on 12 December 1989 (M.P.C. 15576).[10]
