What if a comet hits Earth?
What if a comet/asteroid hits Earth?
Could this be stopped somehow?

Does the sun change its path in the sky throughout the year or does it always go up and down in the same place?
For example, if I always look out the same window, does the sun rise at the same point all year round?
Would it ever be possible to move to planets in our solar system?
We know that there are uninhabitable planets in our solar system. Mercury is too close to the sun and offers barely any resources to support life. Venus is far too hot, and its atmospheric conditions aren't suitable for life. As far as I know, the air is too hot to breathe and consists mostly of…
Why did I choose the topic of exoplanets?
ByPepeal
Have to give a talk on exoplanets. I also have to say why I chose this topic. Does anyone have an idea?
Do we see other constellations above our heads during the day?
So the earth rotates, if it were dark during the day, would you see different constellations?
Depending on the size, we would have bad luck and could do nyx.
Unlike the Dinos, we knew it a few weeks before, but that wouldn’t use anything!
You just start with real experiments, so the investigation and influence of meteorites in space. But until we can stop a continental, or even global killer, a few decades should pass. On the other hand, this only happens every 100 million years…We’re lucky to have some time!
If it’s a big one you can see it quite early, but the possibilities are very rough. So I’d rather hope the case won’t come.
We’d shoot him with tactical nuclear weapons. We’ve got enough! And with 100 atomic bombs there wouldn’t be much left of the asteroid! I see the danger rather in a super earthquake or a super volcanic eruption!
Well…
1. our atomic acts only make small hoppers. To blow up such a thing at 400 or even 1000 km height wouldn’t change anything!
Two. It is questionable how great the influence on a buck that has the size of the Mout Everest! Can you distract him or even destroy him?
3. Even a pulverized Mount Everest would cause some damage.
to 1: Even if you were able to get the rockets into space, they would be too slow – because the asteroid would be on the move with 15 or more km/s. However, the target acquisitions of nuclear weapons are not designed at all. They should finally shoot earthly targets, and cities / bases are immobile.
to 2: In order to distract the asteroids, one would have to hit him far outside (or at least damn long before the impact) (and that very precise) – so that the distraction becomes big enough and he misses the earth.
3: Depends. If the asteroid breaks through the bombardment, but the fragments remain close together, we have the zonk if we can’t keep laying. But if you have enough time to crush the biggest fragments, until they are small enough that they burn in the atmosphere… but for that, you should not only discover the asteroids/competes in the early days, but also in the early days of the day… With our current technology, this is as good as impossible, because all the carrier rockets (of which mankind does not have particularly many) would be too long to go.
You and the atomic bombs. Sure.
Well, at the last time, someone annoyed the dinosaurs a bit. If it wasn’t an asteroid. Come on.
The earth owes its water to comets.
Theoretically yes and currently a mission to an asteroid is on the way to test this.
Fits more often than you think most are killed by the atmosphere, they simply burn in the orbit, a larger comet asteroid, leaving craters the pressure wave would tear down some of it could also cause poisonous gas clouds around it.
but prevent a direct, a what is usually necessary and b yes rockets otherwise exist basically.
There’s a test being made, the DART mission. Next week, the collision will take place with a small asteroid even ned times, with the aim of observing the extent to which its path can be changed.

In a few months, you will know more than today.
For this purpose, the D.A.R.T. Mission held by NASA.
on 26 September the rocket they have built will strike into an asteroid that has an orbit around another asteroid and then you will see if you could significantly change its trajectory.
You can even follow live.
With a 5*10^18 km3 laser gun you can shoot the asteroid.
Well, it could be crushed so that the small parts burn in the atmosphere
