4659 Roddenberry, provisional designation Шаблон:Mp, is a Nysian asteroid from the inner regions of the asteroid belt, approximately Шаблон:Convert in diameter. 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.[2] It was named for American screenwriter Gene Roddenberry.[1]
Orbit and classification
Roddenberry is a core member of the Nysa family (Шаблон:Small),[2][3] 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.[4]Шаблон:Rp
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.[5] 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 characteristics
Roddenberry is an assumed stony S-type asteroid, typical for core members of the Nysa family and in agreement with its high albedo (see below).[2]
Rotation period
In 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 (Шаблон:Small). As of 2018, no secure period has been obtained.[2][6]
Diameter and albedo
According 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,[7][8] 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.[2]
Naming
This minor planet was named in memory of famous American screenwriter, producer and futurist, Gene Roddenberry (1921–1991), known for the Star Trek and Star Trek: 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 (Шаблон:Small).[9]
