PHAs (Potentially Hazardous Asteroids)

[GrapesOfWrath]

This is Ron Baalke's Potentially Hazardous Asteroids site. It has some good reading, and interesting links.

It says there are now 485 known PHAs, which, by definition, might come closer than twenty times the distance to the moon, and are larger than 150 meters in diameter.

Is that close enough to do the orbit insertion thing that BA wrote about in his book?

[GrapesOfWrath]

"closer than" could mean zero. What thing?

[Colt]

Maybe he means swiping one and inserting it into orbit for construction, resources, orbital bombardment, etc. -Colt

I don't remember that in the BA's book. What chapter was it in?

[Colt]

I don't know either, I still have not taken the time to pick up a copy of it. [img]/phpBB/images/smiles/icon_frown.gif[/img] I was only suggesting a possibility of what he might be thinking. -Colt
