2518 Rutllant, provisional designation 1974 FG, is a stony Flora
Orbit and classification
Rutllant is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in the inner main-belt at a distance of 1.9–2.7 AU once every 3 years and 6 months (1,281 days). Its orbit has an eccentricity of 0.17 and an inclination of 6° with respect to the ecliptic.[1] A first precovery was taken at Goethe Link Observatory in 1954, extending the body's observation arc by 20 years prior to its official discovery observation at Cerro El Roble.[8]
Physical characteristics
Rutllant has been characterized as a stony S-type asteroid.[3]

Naming
This minor planet was named in memory of Spanish-born astronomer Federico Alcina (1904–1971), director of the Chilean National Astronomical Observatory (OAN), and professor of mathematics at Federico Santa María Technical University.[2]
Alcina was instrumental for the development of Chilean astronomy, and responsible for a number of critical agreements and decisions, such as moving OAN from Lo Espejo to its current location, for the installment of the
