    We really need to worry about Comet C/2013 A1 (Siding Spring). It's calculated trajectory puts it on a path that could impact Mars on October 19th, 2014. It it does, Mars is toast and the Earth will feel the wrath too (from chunks thrown out into space and in Earth's direction). We could end up with a swarm that could make life miserable here for thousands of years.
