Can a nuke destroy an asteroid?

A nuclear explosion that changes an asteroid’s velocity by 10 meters/second (plus or minus 20\%) would be adequate to push it out of an Earth-impacting orbit. However, if the uncertainty of the velocity change was more than a few percent, there would be no chance of directing the asteroid to a particular target.

Why nuclear testing is bad?

In terms of human exposure, the increase in the thyroidal cancer incidence in many areas of the globe (strongly affected by the radioactive contamination with the 131I radionuclide) is the one among the worst consequences of nuclear testing.

Is it legal to test nuclear weapons underground?

Since the 1963 Test Ban Treaty, the world’s major nuclear powers have tested their weapons underground. The treaty barred nuclear testing in the atmosphere, in space, or underwater.

What is the purpose of underground nuclear testing?

Underground nuclear testing is the test detonation of nuclear weapons that is performed underground. When the device being tested is buried at sufficient depth, the explosion may be contained, with no release of radioactive materials to the atmosphere. The extreme heat and pressure…

What happens when a nuclear weapon explodes in space?

If a nuclear weapon is exploded in a vacuum-i. e., in space-the complexion of weapon effects changes drastically: First, in the absence of an atmosphere, blast disappears completely. Second, thermal radiation, as usually defined, also disappears.

What happens when a nuclear bomb is tested below the ground?

Where nuclear explosions are contained below ground, the outcomes for the test site can be less devastating. The Tatum Dome test site in Lamar County, Mississippi was used to test two nuclear devices in the 1960s. Locals reported the ground undulating like liquid as a result of the blasts.
