}}{{mp|(3708) 1974 FV|1}}, provisional designation {{mp|1974 FV|1}}, is a large Jupiter trojan from the Trojan camp, approximately {{convert|77|km|mi|abbr=off|sigfig=2|sp=us}} 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.[1] The assumed C-type asteroid has a rotation period of 6.55 hours.[5] It is the {{LoMP|3708|lowest-numbered unnamed minor planet}} and belongs to the 50 largest Jupiter trojans.[31]

Orbit and classification

{{mp|1974 FV|1}} is a dark Jovian asteroid orbiting in the trailering Trojan camp at Jupiter's {{L5}} Lagrangian point, 60° behind on the Gas Giant's orbit in a 1:1 resonance (see Trojans in astronomy). It is also a non-family asteroid of the Jovian background population.[7][33]

It orbits the Sun at a distance of 4.4–6.0 AU once every 11 years and 11 months (4,353 days; semi-major axis of 5.22 AU). Its orbit has an eccentricity of 0.16 and an inclination of 13° with respect to the ecliptic. The body's observation arc begins with a precovery taken at Lowell Observatory in November 1930, more than 43 years prior to its official discovery observation at Cerro El Roble.[1]

Physical characteristics

{{mp|1974 FV|1}} is an assumed, carbonaceous C-type asteroid.[5]

Rotation period

In February 1993, a rotational lightcurve of {{mp|1974 FV|1}} was obtained from photometric observations by Italian astronomers Stefano Mottola and Mario Di Martino, using the ESO 1-metre telescope at ESO's La Silla site, Chile. Lightcurve analysis gave a rotation period of 6.553 hours with a brightness variation of 0.23 magnitude ({{small|U=3}}).[5][15]

In January 2015, and February 2016, observations by Robert Stevens and Daniel Coley at the Center for Solar System Studies in California gave two concurring periods of {{val|6.520|0.003}} and {{val|6.55|0.01}} hours and an amplitude of 0.31 and 0.20 in magnitude, respectively ({{small|U=3-/3}}).[5][13][14]{{efn|name=lightcurve-plots-CS3}}

Diameter and albedo

According to the surveys carried out by the Japanese Akari satellite, the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, and the Infrared Astronomical Satellite IRAS, {{mp|1974 FV|1}} measures between 75.66 and 79.59 kilometers in diameter and its surface has an albedo between 0.053 and 0.59.[10][11][12]

The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0531 and a diameter of 79.59 kilometers based on an absolute magnitude of 9.3.[5]

{{Largest Jupiter trojans}}

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 7 October 1987 ({{small|M.P.C. 12323}}).[46]

As of 2018, it has not received a name. This makes {{mp|1974 FV|1}} the lowest-numbered unnamed minor planet (there are more than half a million numbered minor planets with more than 20,000 of them being named). This contrasts with the neighboring asteroid, 3707 Schröter and 3709 Polypoites, that were already named in September 1993 and April 1988, respectively ({{small|M.P.C. 22499/12976}}).[46] The asteroid {{mpl|(4035) 1986 WD}} is the next low-numbered, unnamed minor planet.
