2518 Rutllant, provisional designation 1974 FG, is a stony Flora

Cerro El Roble Station of the National Astronomical Observatory in Chile, on 22 March 1974, and named for astronomer Federico Alcina.[2][8]

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]

Diameter and albedo

According to the survey carried out by the

albedo of 0.77 with a diameter of 3.2 kilometer,[4][5] while the Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.24, derived from the Flora family's largest member and namesake, the asteroid 8 Flora. Consequently, CALL calculates a much larger diameter of 5.9 kilometer, as the lower the albedo (reflectivity), the larger the body's diameter at a constant absolute magnitude (brightness).[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

M.P.C. 10545).[9]
