Posted by tourdemars to General News at February 28, 2013 09:05 PMIn case you just can’t get enough impact news, it looks like Mars may actually get hit by a comet in 2014! As it stands right now, the chance of a direct impact are small, but it’s likely Mars will get pelted by the debris associated with the comet. I know. This is pretty amazing. Still, let me preface this with a caveat: Trying to get precise predictions of comet orbits can be difficult, and for this one we’re talking about a prediction for 20 months from now! Things may very well change, but here’s what we know so far. The comet is called C/2013 A1 (Siding Spring), discovered on Jan. 3, 2013 by the Australian veteran comet hunter Robert McNaught. As soon as it was announced, astronomers at the Catalina Sky Survey looked at their own data and found it in observations from Dec. 8, 2012, which helped nail down the orbit. Extrapolating its orbit, they found it will make a very near pass of Mars around Oct. 19, 2014, missing the planet by the nominal distance of about 100,000 kilometers (60,000 miles).
