NASA scientists propose plan to NUKE incoming asteroids to avoid deadly impacts with Earth
If an asteroid the size of a small village were headed straight toward Earth, there isn’t much we could do on short notice to prevent a major disaster – except blow it up, that is.
----------------------------------------------------------

Sometimes the super smart are about as stupid as someone with severe retardation. If it is close enough those asteroid chunks can and will still come down and hit earth. Something the size of nickel could impact enough damage depending on where it hit or who.

Yeah better to just do nothing

Just like Cancer, the key is early detection. If an incoming asteroid can be detected far enough away, then it doesn't need to be blown apart. A force applied perpendicular to the path can deflect the asteroid so it misses the Earth.

1. If it were the size of a nickel, it would burn up in the atmosphere. It's the larger ones that are a danger.

2. The Tunguska Meteor over Siberia flattened 1500 square miles and it only hit the atmosphere 6 miles up. It never reached the earth.

3. If a nuclear bomb went off even right next to most asteroids it would only send a ripple through it. It would be like hitting a ball of water. Most are not solid rocks make of iron or rock, but smaller pieces of rubble barely held together by miniscule gravity. But even loosely packed dirt can pose a problem if it's a mile across.

4. And finally, what makes nukes on earth so deadly is because we have an atmosphere. Without air in space, where are the shockwaves? What you get is the debris from the bomb and intense radiation.

We need to look at some other method.

It all depends on how far out you intercept the asteroid. If you intercept it far enough out, a photon sail or booster rockets embedded into the surface could impart enough force to veer it off course.
