Wow! Where did you find this info? :o

All of the asteroid data is at http://www.naic.edu/~nolan/astorb.html

This site was the most helpful in writing the algorithms: http://www.davidcolarusso.com/astro/

I'll likely be writing a how-to for astronomers and programmers at some point.

I doubt there's truly that many asteroids in and around Earth. Lol
