Of course that asteroid was only 500 feet in diameter while the Tunguska object was larger than Mount Everest, but even so it might be enough if the deflection occurred a decade or two before the impact. So early detection is the key to success, and that makes comets much more dangerous than asteroids. Asteroids will only come at you from the plane of the elliptic, but a comet could strike from any direction, and a comet will be moving much faster than an asteroid. And if the comet is coming from the direction of the sun it would be even more difficult to spot early. A wide field telescope placed in orbit well outside the elliptic would go a long way toward solving that problem John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis> edk > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
