{{mp|(163243) 2002 FB|3}}, provisional designation {{mp|2002 FB|3}}, is a stony asteroid on an eccentric orbit, classified as near-Earth object and potentially hazardous asteroid of the Athen group, approximately {{convert|1.6|km|mi|abbr=off|sigfig=1|sp=us}} in diameter. It was discovered on 18 March 2002, by astronomers with the Lincoln Near-Earth Asteroid Research at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, in the United States. The Q-type asteroid has a rotation period of 6.2 hours.
Orbit and classification
{{mp|2002 FB|3}} 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. The body's observation arc begins with its official discovery observation at Socorro.
= Close approaches =
The asteroid has an Earth minimum orbital intersection distance of {{convert |0.0034 |AU |km mi |abbr=on |lk=off |sigfig=3}}, which corresponds to 1.3 lunar distances and makes it a potentially hazardous asteroid due to its sufficiently large size.

Physical characteristics
{{mp|2003 QO|104}} has been characterized as an uncommon Q-type asteroid, that fall into the larger stony S-complex.
= Rotation period =
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 ({{small|U=2}}).
= Diameter and albedo =
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, {{mp||}} measures between 1.552 and 1.682 kilometers in diameter and its surface has an albedo between 0.1426 and 0.202.
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.
Naming
This minor planet was numbered by the MPC on 26 September 2007 ({{small|M.P.C. 60678}}). As of 2018, it has not been named.
