It was discovered on 2 March 1981, by American astronomer Schelte Bus at the Siding Spring Observatory in Australia.[1] The likely S-type asteroid has an unsecured rotation period of 12 hours.[5] It was named for American screenwriter Gene Roddenberry.[1] Orbit and classificationRoddenberry is a core member of the Nysa family ({{small|405}}),[5][6] a very large family of stony asteroids, alternatively known as Herta family. It is part of the Nysa–Polana complex, the largest grouping of asteroids in the main-belt. The complex is typically further divided into subfamilies with different spectral properties.[26]{{rp|23}} The asteroid orbits the Sun in the inner asteroid belt at a distance of 1.8–2.9 AU once every 3 years and 8 months (1,334 days; semi-major axis of 2.37 AU). Its orbit has an eccentricity of 0.22 and an inclination of 2° with respect to the ecliptic. The body's observation arc begins with a precovery taken at Palomar Observatory in February 1977, or four years prior to its official discovery observation at Siding Spring.[1] Physical characteristicsRoddenberry is an assumed stony S-type asteroid, typical for core members of the Nysa family and in agreement with its high albedo (see below).[5]Rotation periodIn the 1990s, a fragmentary rotational lightcurve of Roddenberry was obtained from photometric observations by Richard Binzel. Lightcurve analysis gave a highly uncertain rotation period of 12 hours with a brightness amplitude of 0.14 magnitude ({{small|U=1}}). As of 2018, no secure period has been obtained.[5][11] Diameter and albedoAccording to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Roddenberry measures 3.622 kilometers in diameter and its surface has an albedo of 0.193,[9][10] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20, and derives a diameter of 3.56 kilometers based on an absolute magnitude of 14.61.[5] NamingThis minor planet was named in memory of famous American screenwriter, producer and futurist, Gene Roddenberry (1921–1991), known for the Star Trek and The Next Generation television series, and for the Star Trek film franchise.[1] The official naming citation was published by the Minor Planet Center on 18 February 1992 ({{small|M.P.C. 19698}}).[36] References1. ^1 2 3 4 5 6 7 {{cite web |title = 4659 Roddenberry (1981 EP20) |work = Minor Planet Center |url = https://www.minorplanetcenter.net/db_search/show_object?object_id=4659 |accessdate = 17 May 2018}} [1][2][3][4][5][6][7][8][9]2. ^1 {{cite web |title = MPC/MPO/MPS Archive |work = Minor Planet Center |url = https://www.minorplanetcenter.net/iau/ECS/MPCArchive/MPCArchive_TBL.html |accessdate = 17 May 2018}} 3. ^1 2 3 {{cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = A.
