A fair point.
The same applies to you. That's just the "news" that you wrote about is known a long time ago and in the same way a very long time ago everything was calculated by the above-mentioned people from NASA, who are many times smarter than you and are much more competent in this field.
You, in turn, relied on the clickbait of the print press, which in an attempt to earn the last penny from clicks, came up with a loud title for the article, although even in the core of this article there is not a single statement that the collision is bound to happen. It only talks about probability, but you wont believe it, this is not the first such asteroid.
