If you mean, can we see asteroids which may collide with the Earth in a few years time, then I am sure the answer is NO, since they wouldn't be close enough to even see yet.
By the time we find them and determine whether their trajectory is on a collision course with Earth, there will not be enough time to do anything about it.
When you look at the moon, you will see a number of large craters. These craters represent asteroid collisions which, if they had hit Earth, would have caused a catastrophe. The Earth acts as a lens, to focus asteroids onto the moon. That is why, the far side of the moon looks so different to the near side. The far side only has small craters, whereas the near side has a mixture of large and small ones.

An asteroid that could result in the destruction of the earth could very easily go undetected until it was merely hours away!

hi,
there r many predictions and yes science is in the position to predict these asteroids.
1>the use hubble space telescope------->helps in a way not a gr8 asset
2>radio telescopes-------->>>they r the true extreme machines,they work on miniwaves or microwaves rather working on normal radio frequency....as microwaves r disturbance free and give a much clear picture of the space.
bye
hope this helps

Yes. NASA keeps a watch for such asteroids.
