(3708) 1974 FV1 is a carbonaceous asteroid, classified as Jupiter trojan, approximately 80 kilometers in diameter. It was discovered on 21 March 1974, by staff members of the Cerro El Roble Observatory owned and operated by the Department of Astronomy of the University of Chile. It is the lowest-numbered unnamed minor planet.
This dark C-type Jovian trojan is orbiting in the trailing Trojan camp, at Jupiter's L5 Lagrangian point 60° behind its orbit. It orbits the Sun at a distance of 4.4–6.0 AU once every 11 years and 11 months (4,354 days). Its orbit has an eccentricity of 0.16 and an inclination of 13° with respect to the ecliptic. The first precovery was taken at Lowell Observatory in 1930, extending the asteroid's observation arc by 44 years prior to its discovery.
In January 2015 and February 2016, two rotational light-curve for this Jovian trojan were obtained from photometric observations by Robert Stevens at the U.S. Center for Solar System Studies (CS3), California. They rendered a rotation period of 6.520±0.003 and 6.55±0.01 hours with a brightness amplitude of 0.31 and 0.20 in magnitude, respectively (U=3-/n.a.). The results concur with a previously obtained light-curve by Stefano Mottola and Mario Di Martino, using the 1-meter ESO telescope at ESO's La Silla site, Chile, in February 1993. It gave a period of 6.553±0.008 with an amplitude of 0.23 in magnitude (U=3).
