So I'll be first to admit (and sunshine will be first to back it up) that I am a giant space dork. I love to read about space, I love to talk about space and I just love to think about space.
I read
http://www.space.com daily. I was reading an interesting artical about a
Gravity-Powered Asteroid Tractor purposal. The idea is really interesting and I would really encourage other people to read it.
The article itself was interesting (
ink), but it was a small little blurb at the bottom of the artical that got my interest.

In 2029, the 1,000-foot (320 meters) asteroid 99942
Apophis (2004 MN4) will whiz by Earth at a distance of about 18,600 miles (30,000 kilometers). That’s about as close as many geosynchronous satellites. It will swing by the Earth again in either 2035 or 2036, and scientists predict it has a small chance of hitting the planet on this pass.
Thats insane if you ask me. I'm not really worried. If you read all the information its clear that theres still only a small chance its going to hit. Whats cool is that this thing is going to get super close to the earth. In 2029 this thing is going to come with in 18,000 miles of earth. That might not seem close but to give you an idea of how close that is listen to this.
The moon is 239,000 mile (on average) from eath. This thing is coming with in 18,000. Thats insanly close. as the artical says, it comes with in range of satellites that orbit the earth. Of course the thing is, no one really knows for sure. These numbers are based on the limited amount of time Scientists have had to scan the earth. Still, it should get close enough that it will be scene by the naked eye. To me, thats amazing.
Regardless, Apophis is roughly 1,000 feet in Diameter. Its a small little space rock. Its not much of a 'Global Killer', but it would make all the other global disasters we have experianced look petty. Still, no one will really know for sure what will happen when its passes by.
Interesting stuff if you ask me.
Im a firm believer that the biggest threat to earth right now are Asteroids and Massive Volcanos.
