It was discovered on 18 July 2001, by astronomers of the Near-Earth Asteroid Tracking at Palomar Observatory in California, United States.[8] The asteroid was named after American astronaut Rick Husband, who died in the Space Shuttle Columbia disaster.[2] Orbit and classificationRickhusband is a member of the Lixiaohua family, an outer-belt asteroid family of more than 700 known members, which consists of C- and X-type asteroids.[3][11]{{rp|23}} It orbits the Sun in the outer main-belt at a distance of 2.5–3.8 AU once every 5 years and 7 months (2,036 days). Its orbit has an eccentricity of 0.22 and an inclination of 12° with respect to the ecliptic. The body's observation arc begins with its first identification as {{mp|1994 JM|7}} by Spacewatch at Kitt Peak Observatory in May 1994, more than 7 years prior to its official discovery observation by NEAT.[8] Physical characteristicsRotation periodAs of 2017, no rotational lightcurve of Rickhusband has been obtained from photometric observations. The asteroid's rotation period, poles and shape remains unknown.[14] Diameter and albedoAccording to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Rickhusband measures 8.731 kilometers in diameter and its surface has an albedo of 0.048.[5] NamingThis minor planet was named in memory of American astronaut Rick Husband (1957–2003), who was the commander of STS-107 and was killed in the Space Shuttle Columbia disaster on 1 February 2003. The official naming citation was published by the Minor Planet Center on 6 August 2003 ({{small|M.P.C. 49283}}).[16] References1. ^1 2 {{cite book |title = Dictionary of Minor Planet Names – (51823) Rickhusband, Addendum to Fifth Edition: 2003–2005 |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 215 |date = 2006 |isbn = 978-3-540-34361-5 |doi = 10.1007/978-3-540-34361-5_2552 |chapter = (51823) Rickhusband [3.16, 0.21, 11.5] }} [1][2][3][4][5][6][7]2. ^1 2 {{cite web |title = 51823 Rickhusband (2001 OY28) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=51823 |accessdate = 5 September 2017}} 3. ^1 {{cite web |title = MPC/MPO/MPS Archive |work = Minor Planet Center |url = http://www.minorplanetcenter.net/iau/ECS/MPCArchive/MPCArchive_TBL.html |accessdate = 5 September 2017}} 4. ^1 2 {{cite web |title = Small Bodies Data Ferret |work = Nesvorny HCM Asteroid Families V3.0 |url = https://sbntools.psi.edu/ferret/PropertySearch/familyForm.action |accessdate = 5 September 2017}} 5. ^1 {{Cite book |first1 = D. |last1 = Nesvorný |first2 = M. |last2 = Broz |first3 = V. |last3 = Carruba |date = December 2014 |title = Identification and Dynamical Properties of Asteroid Families |journal = Asteroids IV |pages = 297–321 |bibcode = 2015aste.book..297N |doi = 10.2458/azu_uapress_9780816532131-ch016 |arxiv = 1502.01628 |isbn = 9780816532131 }} 6. ^1 2 3 {{cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = A.
