'Planet killer' asteroid found hiding in sun's glare may one day hit Earth
We often hear in science fiction that if an asteroid were to come barreling towards earth, we could somehow either change it&#x27;s trajectory or break it up into multiple pieces by shooting it with a ICBM&#x2F;nuclear weapon&#x2F;etc.<p>What truth is there to this? Suppose this asteroid was on a collision course with earth, would we have any recourse other than praying it lands in Siberia and not NYC.
