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