One is to use nuclear weapons to blow up Apophis, but the trouble is that the explosion is likely to turn Apophis into many small meteorites. After that, these small radioactive meteorites are thrown into unpredictable orbits, and falling to Earth is another injury. This method will keep the earth from being destroyed by a large meteorite, but it will allow the earth to be bombarded by countless small meteorites with nuclear radiation.

I didn't think of why this would be the most heap, even twice as much as the second heap.

The second is to hit Apophis with a spaceship, change its orbit or smash Apophis to pieces. This approach seems to be more effective, but it is just as effective as with nuclear weapons. And it all depends on the strength of the spacecraft, if the spacecraft does not meet the standard, it will cause more serious consequences.

And with less than half a year left, it is estimated that it is too late to build a spaceship. And the existing spacecraft may not be up to par, in case there is a mistake.

The third is to use the whole world to launch rockets at Apophis, and form a booster on the surface of Apophis to accelerate or slow down Apophis. And change the direction of its flight, missing the opportunity to collide with the Earth.

This is the third pile, which I think is ideal. But it is not easy to implement and has certain risks. Because even now, there are only a few countries that can really launch rockets. Exclude small countries that do not understand technology, and certain countries that do not have the same level of technology. If you shoot one and fail to shoot one, then it's a joke.

When I saw this, I glanced up at North Korea, which is a country that has been thinking about launching satellites since 2035 because it can't even play with airplanes. The number of prestigious launches, failures and successes are close to fifty-five. I still make it almost without communicating with other countries, and I don't know whether to praise it or not.

The fourth is to use a laser to diverge the surface material of Apophis outward, thereby generating a reverse acceleration that makes it change the direction of flight. It's a bit fantastical, and I can't understand what's in it. But for this to be successful, it seems that an ultra-high-power laser system is needed. And such a huge laser emission system, the cost and time can be imagined.

The fifth is to use paint to change the color of Apophis, affect Apophis to absorb the heat of the sun, and change its orbit through the change of thermal energy. When I saw this, I began to wonder what I was looking at. How did you change from physics to chemistry all at once? Could it be that after blackening Apophis so that Apophis can absorb some more heat, it will absorb heat like a black sweater? Can hot upwards and cold downwards change the orbit of Apophis?

The sixth is to use a rocket to send a huge kite-shaped solar sail to the top of Apophis, and then open the solar sail to absorb the solar photons as the power, and then open the mechanical arm to produce a sail, and change the trajectory of Apophis by the sail. All I can say is that I can really think about how big a sail it takes to build this thing. Is half a year really enough?

Seven is to put enough gelatinous sponge-like material on the impact surface of Apophis to make Apophis hit the earth. Minimize the damage done by Apophis so that Apophis does not destroy the Earth after he hits it.

Take a hit, as long as you don't die? Isn't this useless work? Even if you hit the real data, it's just a dead America, but if this is made public here, it's not just a return to telling the United States that you're dead. You can do whatever you want in the past six months, who do you want to pull into the water?

I read everything, and Lixia almost finished reading all the ideas.

I could hear that the more Lixia spoke, the more disappointed the more his voice grew.
