Wow, that was highly impressive in my opinion. It really is scary to think about all of the near-earth objects that could potentially slam into the
earth at any moment. Astronomers are really only tracking asteroids and meteors that are large enough to do extensive damage to an area of earth, and
on more than one occasion such an object was not discovered until it had flown by the earth, nearly hitting us in cosmic terms. I mean just look at
our moon, and all of the impact craters it shows on its surface. The earth would look even worse if it were barren and did not have natural processes
to cover the scars of past impacts.
Even smaller objects can cause extensive damage when hitting the earth, if they happen to land in a populated area. The good news however is that the
majority of the earth's surface is covered by our oceans, so statistically speaking there is a good chance that an impact will be in an ocean. But
then again, depending on how large of an impact we are talking about, it may be better for those who are directly in the impact zone, since they will
instantaneously be vaporized and will not have to witness the calamity that will follow.
This is unrelated, but I find myself wondering if our moon will ever become active again geologically speaking. We know that the moon had active
volcanoes at one time, but they appear to be dormant, and unlikely to become active again without some intense heating up. I believe there is only one
volcanically active place in our entire solar system from what we know at this point. I find it quite interesting.
