14505 Barentine           Discovered 1996 Jan. 12 by Spacewatch at Kitt Peak.
John Caleb Barentine (b. 1976) has served as an observing specialist at the Apache Point Observatory 3.5-m telescope and Sloan Digital Sky Survey. Trained in stellar astronomy, he was introduced to planetary work by colleagues Gil Esquerdo and Carol Neese, who suggested this name.
