There is no way to determine an exact number for just in our Solar System, let alone all of space. The number keeps changing as they collide with each other either breaking off smaller asteroids or fusing together forming larger asteroids, or collide with planets or the sun and are destroyed. We can't see them around other stars, but there are inevitably some.
