Comet c2013 On A Possible Collision Course With Mars in 2014

[QUOTE=Garik;39770262]Scary my ass, you'd need something the size of earth to majorly affect it's orbit.

1.3 cm/s does something, but it's so minor it might as well be nothing.[/QUOTE]

Considering most impacts probably alter the velocity of a planet's orbit by like MICROMETRES if not NANOMETRES per second (if not less) it's kinda scary.

The asteroid that supposedly killed the dinosaur was like 10 KM in diameter. This thing is like 50 KM in diameter and is hitting a planet smaller than the Earth. The amount of energy we're talking about here is absolutely terrifying.

Yeah, except it's orbit change is minuscule and the chance of any debris flying at us is even more minuscule.
