Update: Comet Close Flyby of Mars in 2014 October

Based on data through April 7, 2013, the latest orbital plot places the comet's closest approach to Mars slightly closer than previous estimates, at about 68,000 miles (110,000 kilometers). At the same time, the new data set now significantly reduces the probability the comet will impact the Red Planet.
