That's the sort of clickbait headline so egregious that one should negatively judge the publication that used it forever after. Buried in the article: "Impact from the asteroid could be devastating, but thankfully, it does not pose a threat to the planet. The asteroid will fly by the planet at a distance 3.9 million kilometres - a distance greater than 10 times of that between the Earth and the moon."
"NASA warns hazardous asteroid heading to ward Earth" Not to sound ungrateful, but I think I speak for everyone when I say it's about time that asteroids protect us.
