2691 Sérsic, provisional designation Template:Mp, is a stony Florian asteroid and binary system from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered by staff members at the Felix Aguilar Observatory at El Leoncito Complex in Argentina, on 18 May 1974.[1] The asteroid was named after Argentine astronomer José Luis Sérsic.[2]

Classification and orbit

Sérsic 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 2.0–2.5 AU once every 3 years and 4 months (1,228 days). Its orbit has an eccentricity of 0.11 and an inclination of 4° with respect to the ecliptic.[3]

Physical characteristics

Diameter and albedo

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of this orbital family – and calculates a diameter of 6.21 kilometers with an absolute magnitude of 13.2.[4]

Satellite

Sérsic is a binary asteroid. A minor-planet moon was discovered in 2011 from lightcurve observations of the asteroid. It has a diameter of 2.15 ± 0.11 and an orbital period of 1 day, 2 hours, and 48 minutes.[4][5]

Naming

This minor planet was named in honor of José Luis Sérsic (1933–1993), well known for his work in extragalactic astronomy and on supernovae (also see Sérsic profile and Template:Section link). He has served as director of the Córdoba Observatory.[2] The approved naming citation was published by the Minor Planet Center on 20 February 1989 (M.P.C. 14207Script error: No such module "Check for unknown parameters".).[6]
