As of March 2013, the estimated chance of impact was about 1 in 2000. As of April 2013, the odds of a Mars impact were about 1 in 8000. The 8 April 2013 JPL 3-sigma solution was the first solution to show that the minimum approach by the comet would miss Mars. As of 8 April 2013, the odds of impact were only 1 in 120,000 ... With an observation arc of 428 days, the nominal pass is 0.00096 AU (144,000 km; 89,000 mi) from the center-point of Mars and the uncertainty region shows the comet will not come closer than 0.00086 AU (129,000 km; 80,000 mi). http://en.wikipedia.org/wiki/C/2013_A1
