Four Times Over
Less than the total number in existence right now ! Countries around the planet have enough nuclear warheads to destroy every living thing on earth many times over !
no never because stars are a thousand times bigger than earth and the ball of flaming gas would destroy earth before it even touched it.
It is possible to test a nuclear weapon in space, but it is banned. Nuclear weapons have been exploded in space. In 1962 starfish prime test exploded a 1.4 megaton bomb (~100 times bigger than the Hiroshima bomb) was detonated 400 km over the central pacific. The electromagmetic pulse (called an EMP) damaged communications and electronics from Hawaii to New Zealand (a distance of 7000 km). If this was done today it would cause billions of dollars in damages by wiping out computer systems and satellites over an area of millions of square kilometers. The gamma energy of a nuclear weapon is normally turned into heat when exploded in the atmosphere but in space there is no atmosphere to heat up so all the gamma energy is turned into an EMP that fries electronics. Just one bomb exploded over the United states at 500 km would destroy all computers and electronics that were turned on at the time in the entire country. Military electronics are hardened against this.
Io has a radius 0.286 times that of the Earth and a volume 0.01 times that of the Earth.
Jupiter has about 300 times the mass of Earth and about ten times Earth's radius. Estimate the size of g on the surface of Jupiter
Once, because the first time The USA, UK, Canada and France will attack instantly after the first!
Surprisingly few ! The 'super powers' have enough nuclear weapons between them - to destroy humanity many times over !
not worth thinking about , a nuclear war would in itself be a chain reaction causing humanitys elimination . the earth cannot be destroyed but we can .
The most destructive weapon on earth is the hydrogen bomb. These weapons are potentially thousands of times more powerful than ordinary atom bombs (which use nuclear fission rather than fusion) and could easily destroy a city in seconds.
Anything after 'once' is academic

Well their are no disadvantages to nuclear plants, if your using them for nuclear power, as nuclear power is the safest type of energy in modern times. However disadvantages of nuclear weapons include well the ending of the planet, the possibility of it being stolen by terrorists or even it being spied on for another nation so it can create nuclear weapons.
As stated, the question is overly obvious; the world can be destroyed only once because once it is destroyed, there is nothing left to be destroyed, right? How many times could the same ceramic dish be shattered? More than once, but only if you are willing to glue it together again, and if the whole world were to be shattered, there would be no one left to glue it together again (unless you are expecting aliens from outer space to take an interest). However, you might have been thinking of the principle of overkill, that the nuclear arsenals of the world contain more weapons than would be needed to destroy the entire world. At a rough guess, the total inventory of nuclear weapons in the world is sufficient to destroy a dozen worlds at least (if we had a means of getting to other worlds, of course). But the Earth can be destroyed only once.
Nuclear weapons take their energy from the Strong Nuclear force that holds the atomic nucleus together.Conventional weapons take their energy from the Electromagnetic force that holds electrons in orbitals around the atomic nucleus.The Strong force is a couple thousand times stronger than the Electromagnetic force.
theoretically the yield of nuclear weapons is unlimited.
Nuclear weapons have been used in war twice- both times in 1945, when the US bombed the Japanese cities of Hiroshima and Nagasaki.
The way you can destroy the world with nukes is to combine 17 trillion times the world's nuclear power, send them off to the moon, and speed them up to 1500 MPS while orbiting, then set a course for Earth. In other words, impossible.To destroy the Earth, like really destroy it, you need a an object twice the size of mars, made of iron, to crash into the earth. This would effectivey shatter the crust, shoot the mantle out into space, and make the core a new, miniture planetoid without an atmosphere.Planting 30 nukes in every country around the world. BOOOOM!!
