Planet-Killer Asteroid Headed Toward Earth: Better Get Toilet Paper
While I meant for the headline to be funny, it's no joke about the asteroid. NASA is tracking a gigantic, 2 1/2 mile wide asteroid that will approach Earth next month. An asteroid that size would be a planet-killer as the impact would send so much debris into the atmosphere it would block out the sun long enough for 70% of life on Earth to die. You know the story, you've seen the movies. While this type of asteroid does not generally cross Earth's path, it will be close enough for NASA to consider it potentially hazardous.
