yeah I have read this article before this. Asteroids interest me. What really are the chances we will see a collision in this life time or our childrens? 1-250,000 chance is still one heck of a chance. Although its amazing we have missles that can shift the route of an asteroid larger than a couple football fields. 😎

The thing is 25 years away and they know its 885 feet long? How can they possibly measure the length of that down to +/- 5 feet?

Well, I'm not an astronomy major by any means, but sensor technology has come a long way.

25 years away isn't really that far considering how far away the closest stars are. We can observe it, observe it's rotation along its axis' and we can get it's shape on a 3d level, and figure out the approximate distance between the two farthest points.

If we can measure its size within a few feet from 25 years away traveling say 15-20,000 MPH and we know it will pass us by 18,000 miles, why do anything to it?

I would guess because trajectory is harder to observe in an object then it's size?

I really don't know.

Because we like blowing stuff up.

War is an extension of economics and diplomacy through other means.

Economics and diplomacy are methods of securing resources used by humans.

Securing resources is the one necessary behavior for all living things.

War = Life

Well this is surely true.

The main issue is potential impact, the current estimate of yield is 880 Megatons. The Tunguska Event yield is estimated at the high to have been 30 Megatons and took down all the trees in a 16.25 mile radius. But while Apophis is small and not a 15km long ELE, it is a big bruiser capable of massive destruction the likes of which we haven't seen since Krakatoa at 200 Megatons.

It used to have a much higher threat level, but now we have to wait until after its 1st pass to know if 2036 is the real threat of not.

The best safest way to get rid of it is to use a gravity tractor not a direct energy transfer attack

Do we have the technological means to do that? I've never heard of that before, except in sci-fi.
