Hi Geo students! You would remember that I spoke about Comet ISON in class. Well soon enough we will learn a little bit more about Comets but I need you to note that a Comet is generally an icy space rock which varies in size, sometimes miles in diameter. This one called ISON is entering our Solar System for the first time and will whip around the sun in a few months time. We should be able to see it with the naked eye from October. Check out the video and let me know what you think.
