It is rare for astronomers to be able to see an asteroid that is going to hit the Earth, but it DID happen in 2008. The asteroid 2008 TC3 was seen about a day before it landed. The fireball was visible from airliners hundreds of miles away, but I do not believe that any actual impact crater has been located. The reason why it is so rare to see an asteroid before it hits are, one, most things that hit the Earth are pretty small, and difficult to see in space. And two, if it is going to hit the Earth, then the bearing of the object won't change; it won't appear to move across the sky, but just be sitting right there in the sky looking like a dim star. And until it gets really close, no one will notice that is getting closer and closer!
An asteroid (not "astroid" - watch the spelling) and a meteoride is basically the same; if it has more than about 10 meters in diameter it is called an asteroid. A meteor is the name given to a meteorite that falls into Earth's atmosphere.
