3749 Balam /ˈbeɪləm/ is a stony Flora asteroid and rare trinary system orbiting in the inner regions of asteroid belt. It also forms a secured asteroid pair with sub-kilometer sized asteroid (312497) 2009 BR60.[5] Balam was discovered on 24 January 1982, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station near Flagstaff, Arizona, and received the prov. designation 1982 BG1. It was named after Canadian astronomer David Balam.[15] Balam measures approximately 4.1 kilometers (2.5 miles) in diameter.[5] Its two minor-planet moons have an estimated diameter of 1.66 and 1.84 kilometers, respectively.
