3040 Kozai, provisional designation 1979 BA, is a stony asteroid and Mars-crosser on a tilted orbit from the innermost regions of the asteroid belt, approximately 4 kilometers in diameters.
The asteroid was discovered by American astronomer William Liller at Cerro Tololo Inter-American Observatory in Chile, on 23 January 1979, and named after Japanese astronomer Yoshihide Kozai. It is considered a classical example of an object submitted to the Kozai effect, induced by an outer perturber, which in this case is the gas giant Jupiter.
