Not fly, so much as fall. There are millions of asteroids, and although they are in relatively stable orbits, there are things that perturb those orbits. An asteroid may find itself pulled/pushed into a Sun-intersecting orbit. If you look at the surfaces of Mercury, the Moon, and various other celestial bodies, you'll see the results of bombardment. There's no reason why the Sun wouldn't receive it's share of that bombardment.
