Comet may give Mars a close shave in 2014
Coonabarabran, Australia (UPI) Feb 27, 2013
A newly discovered comet is heading for Mars and should give the red planet a close fly-by in October 2014, Australian astronomers say. Comet hunter Robert McNaught at Siding Spring Observatory in New South Wales, Australia, discovered the object dubbed C/2013 Jan. 3. Additional data on the comet's movements by the Catalina Sky Survey in Arizona allowed astronomers to trace the comet's likely orbit around the sun. Its calculated trajectory has the comet crossing Mars's orbit on Oc ... read more
