Scientists have no idea when the next city-killing asteroid is coming – Quartz
sigh...kya fayda... !
We have developed satellite intercepting missiles that can be equipped with nuclear warheads to intercept such a bogey.
However for any appreciable impact on such an object, it would have to be intercepted far from the earth, so that rather than trying to destroy it outright, a nudge to it's trajectory can be given so that it would Miss earth.
That's like trying to hit a pea at the other end of a football field when it's coming towards you at a few hundred kms per hour.
So Yeah we are doomed that ways. Someone keep Harry Stamper on speed dial.
The point this article makes is that we have to know about it a least a year early.
This asteroid was detect by a Spanish dentist and not these fancy astronomer with fancy equipments, so if we fail to detect, there is no way we can take evasive action.
Nukes wont stop something moving THAT fast .. timing required to detonate a nuclear weapon in the upper atmosphere while trying to hit an object which travels about 15km in a second.
Satellite launch vehicles achieve about 11.8 km/s when they're launched into orbit.
Most importantly we can hardly track these meteors which are inbound ..
^^ not to stop.. but to nudge its trajectory!
Unless you plan to strike it way out in space .. for which you will need to launch days in advance. A Nuclear explosion in outer space will only generate heat & energy, there won't be any "force" in its explosion. Only way to deflect a meteor would be to strike it with an object of comparable momentum ..
best bet is to quickly colonize another planet .. before big blue turns into space dust
