Could a Comet Hit Mars in 2014?
By Ian O’Neill | Discovery News
A recently discovered comet will make an uncomfortably-close planetary flyby next year — but this time it’s not Earth that’s in the cosmic crosshairs.
According to preliminary orbital prediction models, comet C/2013 A1 will buzz Mars on Oct. 19, 2014. The icy interloper is thought to originate from the Oort Cloud — a hypothetical region surrounding the solar system containing countless billions of cometary nuclei that were outcast from the primordial solar system billions of years ago.
We know that the planets have been hit by comets before (re: the massive Comet Shoemaker–Levy 9 that crashed into Jupiter in 1994) and Mars, in particular, will have been hit by comets in the past. It’s believed Earth’s oceans were created, in part, by water delivered by comets — cometary impacts are an inevitable part of living in this cosmic ecosystem.
C/2013 A1 was discovered by ace comet-hunter Robert McNaught at the Siding Spring Observatory in New South Wales, Australia, on Jan. 3. When the discovery was made, astronomers at the Catalina Sky Survey in Arizona looked back over their observations to find “prerecovery” images of the comet dating back to Dec. 8, 2012. These observations placed the orbital trajectory of comet C/2013 A1 through Mars orbit on Oct. 19, 2014.

Shoemaker-Levy 9 (1994) This comet’s crash with Jupiter in 1994 was the first observed collision of two solar system bodies. The crash produced plumes thousands of miles high, gas bubbles and dark scars in the atmosphere. Shoemaker-Levy 9 was also the first comet to be seen orbiting a planet, instead of the sun. Jupiter most likely captured the comet into orbit in the 1960s or 1970s.
