How much water will it take to put out the sun?

No amount of water will extinguish the sun. Water is H2O, two hydrogen and one oxygen. In fact, a sufficient amount of water will only add fuel for the sun, as the oxygen molecules split into their constituent atoms under the intense heat, and more hydrogen is supplied for the reaction.

Is it possible to put the sun out with water?

The probable answer is “no.” The Sun involves a special type of fire that is able to “burn” water, and so it will just get hotter, and six times brighter. Water is 89\% oxygen BY MASS. And the Sun’s overall density is 1.4 times that of water.

How does the sun burn if there’s no oxygen in space?

The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. Hydrogen really doesn’t burn, it fuses, into helium. So no oxygen is required!

What keeps the sun spinning?

Nothing keeps the sun spinning. The sun spins under its own inertia and does not need any help to keep it going. Isaac Newton observed that objects in motion tend to stay in motion. This is called the Law of Inertia.

Is it possible to put out the Sun with water?

First of all, you cannot put out the sun as if it were a fire. As David Belk pointed out, you’ll just be giving the sun more fuel. However, water contains both hydrogen atoms (which is the primary fuel for stars in the Main sequence), and oxygen which is a product and a fuel much later in a star’s evolution (see Stellar evolution).

How much water would it take to extinguish the Sun?

No amount of water will be able to extinguish the sun. Firstly the gravitational potential energy of the water will be converted to kinetic energy when it falls to the surface of the sun, causing it to dissociate into Hydrogen and Oxygen which will only add more fuel for the nuclear fusion processes in the sun.

What would happen if we fed the Sun more oxygen?

As of right now, only 0.8\% of the Sun’s fusion reactions proceed along this path. So if you fed the Sun more oxygen as part of the water, it would allow it to perform more of these fusion reactions too.

Is it possible to extinguish the Sun?

You cannot extinguish the sun like that, at least not the way you think. You can only put out a reaction based on combustion with water because it needs oxygen to sustain it. The water evaporates immediately, thus forming a dome of steam around the fire that cuts off the oxygen supply, thus extinguising it.
