2691 Sersic (1974 KB) is a main-belt binary asteroid[3] discovered on May 18, 1974 by Félix Aguilar Observatory at El Leoncito.[2]

It was named in honor of José Luis Sersic (1933–1993), well known for his work in extragalactic astronomy and on supernovae (also see Sersic's law and Lenticular galaxy § Sérsic decomposition). He has served as director of the Córdoba Observatory.[2]

Satellite[edit]

A moon was discovered in 2011 from light curve 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.[3]
