A comet is on course for a super-close approach to the planet Mars this Sunday (Oct. 19) in a rare celestial encounter. And if you have a moderate-size telescope, you just might be able to spot the icy wanderer as it nears the Red Planet, weather permitting.
The comet in question is Comet Siding Spring, which was discovered on Jan. 3, 2013 by the Scottish-Australian astronomer Robert H. McNaught, a prolific observer of both comets and asteroids. McNaught has discovered 82 previously unseen comets, including a stupendously bright one that briefly became visible to the naked eye in broad daylight in January 2007.
