Is this article about the same asteroid?

I must admit, the article is so full of errors and goofy sentences as to be hilarious (in a way).

Different asteroid. I doubt firing a missile at an steroid would work. Even if it were hit, the asteroid in the article is over 300 meters across. It’s not going to make much difference.
