How much heat can a asteroid impact explosion be.?

Question

I just want to know how hot is a asteroid impact explosion,i read that it really really hot went it impacts,they say that if it 10 miles wide moving at 75,000mph,it can vaporizes anything within many hundreds of miles,how hot is a explosion from a asteroid impact compar to a nuclear blast,i have read that it can be 4 to 700 times hottest then the surface of the sun,but can it be millions of degress like a nuclear blast is.

Answer 1

The heat from a asteroid impact comes from the conversion of kinetic energy (KE) into heat energy. The bigger and faster the asteroid is, the more KE it has. Which means more heat when it hits.

A 1 km asteroid at typical speeds would have the impact energy of about 300 gigatons of TNT. Because the energy is spread out over many kilometers, the temperature would be "only" about 17,000 C, and would quickly (a few dozen seconds) cool down to 5000 C.

Answer 2

It would be a difficult calculation but I saw a show on the discovery channel on that subject and they were talking about a 1/2 mile wide (1 km) asteroid having more energy than all the nuclear weapons on earth.

Answer 3

particular, whether it particularly is academic, somewhat than having any actual effect such as you could routinely anticipate from this type of intense temperature. At effect, the potential of action of a massive asteroid is all switched over to warmth, in an exceedingly small area and an exceedingly couple of minutes, subsequently till it has time to opened up, there is mathematically an exceedingly intense temperature certainly. whether it may't be sustained; it falls so at as quickly as, because of the fact the nice and snug debris scatters, that there is not any time to degree it, or for it to warmth the rest as much as extra effective than a fragment of its very own temperature.

Answer 4

Depends on how big the asteriod is going to be.
