4659 Roddenberry, provisional designation 1981 EP20, is a Nysian
Orbit and classification
Roddenberry is a core member of the
405),[3][4] 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.[9]
: 23
The asteroid orbits the Sun in the
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.[2] 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).[3]

Diameter and albedo
According to the survey carried out by the
albedo of 0.193,[5][6] 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.[3]
