2002 FB3 is a member of the Athen group of asteroids. It orbits the Sun at a distance of 0.3–1.2 AU once every 8 months (243 days; semi-major axis of 0.76 AU). Its orbit has an eccentricity of 0.60 and an inclination of 20° with respect to the ecliptic.[2] The body's observation arc begins with its official discovery observation at Socorro.[1]
(A) List includes near-Earth approaches of less than 5 lunar distances (LD) of objects with H brighter than 18. (B)Nominal geocentric distance from the Earth's center to the object's center (Earth radius≈0.017 LD). (C) Diameter: estimated, theoretical mean-diameter based on H and albedo range between X and Y. (D) Reference: data source from the JPL SBDB, with AU converted into LD (1 AU≈390 LD) (E) Color codes: unobserved at close approach observed during close approach upcoming approaches
In March 2016, a rotational lightcurve of this asteroid was obtained from photometric observations. Lightcurve analysis gave a rotation period of 6.231 hours with a brightness amplitude of 0.19 magnitude (U=2).[7]
The Collaborative Asteroid Lightcurve Link assumes a stony standard albedo of 0.20 and calculates a diameter of 1.49 kilometers based on an absolute magnitude of 16.5.[3]
Naming
This minor planet was numbered by the MPC on 26 September 2007 (M.P.C. 60678).[9] As of 2018, it has not been named.[1]
