Asteroids are one of the most serious threats to life on earth that we know of. This is not something we think about very often. It was almost certainly an asteroid that took out the dinosaurs. This is a very real threat that humanity faces. The good news is that scientists are getting better at watching out for these large rocks which whiz by our planet more often then you might think. The bad news is that, today there is very little we can do about one of these striking us. See my rant at the end of this article for more about what we can do.
This week it was reported that a massive asteroid, called 99942 Apophis, is going to make a very close pass of Earth in 2029, and that flyby could determine the fate of our planet.
“We can rule out a collision at the next closest approach with the Earth,” Astronomer Alberto Cellino told Astrowatch. “But then the orbit will change in a way that is not fully predictable just now, so we cannot predict the behavior on a longer timescale.”
The flyby in 2029 will be very-very close, with the asteroid expected to pass within 20,000 miles of Earth’s surface. That’s a ridiculously close by space standards, and it’s such a tight squeeze that the gravity of Earth is expected to alter the path of Apophis in such a way that its future passes will become much more unpredictable until further forecasting can be accomplished.

My Asteroid Influenced Rant
All of this talk of potential global doom from space kind of makes you think that we should be working together as opposed to engaging in endless political arguments. Our combined energy should be used to better ourselves and collectively protect each other. The type of healthcare we have, or what political ideology we each have will help us ZERO if we can’t prevent a rock like 99942 Apophis from striking our little blue marble. Instead of engaging in endless arguments we should collectively science it up and work on preventing disasters like the one that is possible in 2029.
OK – now I need to go watch an episode of Star Trek.
