    Another worthwhile cosmic event is going to happen October 19th. A comet being called Siding Spring will pass within 87,000 miles of Mars. To put that in perspective, that's less than half the distance between the Earth and the moon. So, pretty close. And this is a super rare occurrence too, supposedly only happens once in a million years.

    2:27 pm EST is when its supposed to be closest to Mars. Likely only people in southern hemispheres will be able to see it first hand, if they have some strong binoculars/telescopes pulled out. But the rest of us will still get to see, if you check out NASA's site the day of, or anytime after of course.

    As for relevance of what we can take away from this event, aside from it being awesome in and of itself, ABC outlines it pretty well:

    The comet is comprised of icy debris that researchers believe are remnants from the formation of the solar system. Its dramatic brush past the Red Planet is expected to yield new insights into the materials that existed during the formation of the solar system 4.6 billion years ago.

    I feel like we are pretty lucky with all these rare cosmic events seemingly happening all the time now.
