Quoting: Anonymous Coward 50016578 The closest approach to Earth is 40 million miles, I think we can safetly say it will not affect us.we are going right through it's cloud, in mid January. What makes you so confident? in 1014 it is KNOWN, or at the very least strongly suspected that a comet fragment tsunami inundated England and Wales, and probably the Americas too, based on ice core data from Greenland. It is nothing new for Earth to pass through a Comets tail, that is where we get meteor showers from. [ link to science.nasa.gov] "For several days around January 12, 2014, Earth will pass through a stream of fine-grained debris from Comet ISON," says Wiegert. "The resulting shower could have some interesting properties. According to Wiegert's computer models, the debris stream is populated with extremely tiny grains of dust, no more than a few microns wide, pushed toward Earth by the gentle radiation pressure of the sun. They will be hitting at a speed of 56 km/s or 125,000 mph. Because the particles are so small, Earth’s upper atmosphere will rapidly slow them to a stop. Like sparkles in the sky.
