Asteroid Bennu reaches highest impact risk level

[QWECXZ]

Thats the problem, we have no device to bring 60 million tons to reach escape velocitive. The sad truth is, not even the russian tsar bomb could blast up Bennu and thats a small obejct. A large one like Chicxulub would totally **** us up xD

You know i always wonder what the Chicxulub impact was like. Its so drastic...one day earth is a paradise and one hour later a global hell.

Its also funny how we humans brag with our weapons and compared to that...eve all nukes combined are nothing.

But why do we need 60 million tonnes?
All we need is a missile that works like a bunker buster. It has enough velocity to penetrate the object deeply and then explodes. We don't have shock waves in vacuum, but shock waves can travel in solids.

Blowing it up will split it into a few smaller pieces, now you have multiple space rocks trying to kill you. Maybe changing its direction by blowing up nukes near it or landing thrusters on it will work.

But its not solid. Its a rubble pile. It would wobble and then stabilize again. Rubble piles are not very well understood yet.

It is not Asteroid the world should be looking for but rather comets these are unpredictable and way more dangerous than any asteroid because they can be in far outer space in one second and than 30 seconds later cause an impact. They also move in a much faster speed hence the power of impact would be much greater. No computer can predict a comet landing it can come out of nowhere and change course sporadically.

Asteroid are a bit like the solar system they travel around the sun or earth in a set and fixed orbit just circulating in that orbit they are predictable but with comets that is not the case. Their rule of engagement is different they are mostly in the far outer space far far beyond the sun where it is cold and icy they follow no orbit pattern just hovering allover the place it is an addresse less icy rock hence it can be one second in the far outer space and if it somehow changes direction can cause impact in short time without any previous knowledge of it whatsoever

right now it is too early to judge. We need more data on its orbits. It is 100+ years away. When it gets to ~50 years away we'll have a better idea of how the orbit is evolving.

But let me correct you with math. You can indeed blow it up such that the small pieces will burn up in the atmosphere or completely miss the Earth. It weighs 7.1x10^10 kg. 500 m across (250 m radius). Gravitational binding energy: 853.6 x 10^6 joules. Gravitational binding energy is the energy required to overcome an object's internal gravity and explode it completely and permanently because all pieces will have attained escape velocity from each other.

Bunker buster Tsar Bomba (50 MT) that explodes in the middle of the asteroid: 2.1x10^17 joules. Tsar Bomba would completely vaporize this shit.

And that right away rejects your own claim that it cannot explode because the pieces will collapse into a single mass under its own gravitation.

Nevertheless, it is possible to destroy it. But my initial fact remains intact. We do not know how this slight changes can affect other planets due to the chaotic nature of the N-body problem.

It doesnt affect anything because its far too small.

As for exploding, we simply dont know how it reacts. Its large rocks, clumped together and the space between filled with small pebbles, sand corn sized grains and so on. It might just wobble around. The thing is, before explosion you have 60 million tons mass and after explosion you still have 60 billion tons mass. You make a single "bullet" into a pump gun shot in worst case

It's too early to tell what will happen when it's closer in terms of time till the impact date then we will surely know for now we can anticipate, but many aspects will come into play, other planets will certainly affect its course as time passes. In space even centimetres matter.

Not necessarily. What if you hit it with something that releases something made mostly of particles similar to its anti-matter particles?
That will immediately convert most of its mass to energy. Problem solved.

Nevertheless, what I said is not about the lack of a method to solve the issue, but the consequences of solving it.

There wont be any consequences. No asteroid in the solar system is big enough to cause any noticeable effects when removed.

Look at Triton. Its a huge moon which will be destroyed in a relative short time span. Not much will change.

Read more about chaos theory and you won't be so confidently arguing about size anymore.

Even extremely small, and by extremely small I really mean extremely small (sometimes beyond our means of observation and computational power) can have extremely unpredictable consequences in long term, not only to the values of the solution, but even the shape of the solution.

Even to this date, we do not know if the solar system is stable or not. Lots of mathematicians have tried to prove the stability of our solar system and all of them have failed. I think Kolmogorov has proved some results that under some conditions the solar system is likely to be stable but I do not remember it anymore because I read about it years ago.

Even to this date, we do not know if the solar system is stable or not. Lots of mathematicians have tried to prove the stability of our solar system and all of them have failed. In fact, there is a very high probability that the solar system is not stable and I think Kolmogorov proved a theorem that the set of good solutions (stable ones) is in fact in a sense a very small set (it is a measure zero set). I do not remember it anymore because I read about it years ago.

Exactly even the diminutive change can lead to different outcomes in space and we are talking about something which is a century away.

As the joke goes, it's not the bullet with your name on it that should worry you, but the one addressed '..To whom it may concern...'

Mercury is the one planet that might go rough in next 4 billion years.
