How much ice does it take to extinguish the sun, and can ice as large as Mars extinguish the sun?

In fact, you can't extinguish the sun with ice.

Nuclear fusion takes place in the sun. It is a nuclear reaction in which elements such as hydrogen and helium are synthesized into heavy elements.

The answer is no. Because of solar nuclear fusion, not only because it is mainly composed of hydrogen and helium, but more importantly, because of its huge volume and mass, enough pressure is enough to heat up to more than 10 million degrees Celsius to ignite fusion. If you take a piece of ice the size of a planet and throw it at the sun, the end result is that the sun is more massive, and the ice is composed of 2 3 (the amount of matter) hydrogen, which is the ideal fuel for nuclear fusion.

In the end, you will find that using ice to extinguish the sun is just adding fuel to the fire.

On Earth, the fuel for hydrogen bombs is refined in water.

If the size of this ice is larger than the sun. You will find that the weight of the ice itself is also greater than that of the sun, and at this time, the temperature of the ice core also rises sharply due to the pressure, and before you can extinguish the fire of the sun, you find that your ice has also started nuclear fusion in the core. Your ice has become another star.

In fact, as long as the mass is large enough and the composition is reasonable (e.g. your ice contains a lot of hydrogen), new stars will be born.

The sun is not a chemical flame at all, so there is nothing you can do about the heat of the sun with ice (you probably think of physical cooling).

In fact, the fundamental cause of the sun's nuclear combustion lies in its mass. When the mass of a celestial body reaches a certain level, the temperature and pressure of its core trigger hydrogen fusion, which gives birth to a star. From this point of view, no matter what you throw at a star, even if it's ice, or even other gases in liquid or even solid form, the temperature is as low as close to absolute zero, it's all adding to the star's flames.

The more mass increases, the higher the temperature and pressure in the core of the star, the faster the hydrogen fusion, the faster the production rate and therefore the brighter it is (this law is Eddington's law of mass light).

Of course, the faster a star burns out, the sooner it burns out. If you could increase the mass of the Sun by a factor of hundreds, it might burn up its hydrogen fuel and cause a supernova explosion in a few hundred or even hundreds of thousands of years. This can be regarded as "extinguishing" the sun.

Of course not.

The Sun is much larger than Mars.

And the sun is far, far away from Mars.

The mass of the Sun is about 3 million times that of Mars. So a little ice? If a firefighter had extinguished the fire at the World Trade Center with a popsicle, it wouldn't have killed so many people.

Moreover, the main component of ice, 2 3 is hydrogen (the amount of matter), and throwing it on the sun will only make the sun increase the fusion fuel and burn more vigorously.

Of course not, the Sun is a large fireball, much larger than Mars, Mars is very far from the Sun, and even if it is close to the Sun, it will be dried by the Sun, and it is impossible to extinguish the Sun.

It's impossible, the sun has reserve energy, you destroy him, he catches again.
