Near Earth Asteroid Website from NASA, Interesting Asteroid Information

This is the nasa website for the tracking of near earth objects. This site is scarier than alot of the crap I've seen even though it's just data on the asteroids. What gets me is the number of close calls. Just browse through this site and tell me what you think. I am not up on all the technical stuff but the lists are very scary to me. neat.jpl.nasa.gov...
