Could an asteroid be big enough to do any kind of damage to the sun?

We always hear about the possibility of an asteroid hitting the earth, which could cause tremendous damage. 
I've never heard wether it's even possible for an asteroid to hit the sun and even if so, what exactly would happen?

No. Asteroids are, per definitions pretty much, small. Asteroids (or at least icy ones) can't be larger than Ceres (950km diameter). Otherwise they would be (dwarf) planets. The Sun wouldn't even notice being impacted by such a body. Even a large object, like the Earth, wouldn't be able to damage the Sun. It would be able to affect its rotation and maybe cause a huge explosion (depending on how it impacts), but it wouldn't be able to do much permanent damage.
