From what I understand, the outgassing is what _causes_ the possibility of hitting the Earth (non-gravitational disturbances make the orbit hard to predict, and it's _possible_ that it might hit the Earth). We won't be able to revise the probabilities (has anyone gotten the "official" chances of it hitting the Earth?) until it is on approach. I'm of the opinion that we'll have plenty of time to deflect it if it's determined to be a significant threat, as long as we get our butts in gear. ---------- Erik Max Francis Omnia quia sunt, lumina sunt.
