8 steps of the Sun before dying

Not only the Earth or planets but also the Sun itself must follow the law of nature, nothing will exist forever. But how will it change before the Sun dies? And how long does that change take? Please see the article below for more details.

About 1 billion years later, the Sun will begin to change.The hydrogen gas in the core will gradually disappear, the temperature will increase.Therefore, its surface will be brighter and have a big impact on the Earth.The temperature of the Earth's surface will then be around 75 degrees Celsius. The oceans will evaporate, the Earth becomes a lifeless steppe.

When the Sun uses up all the hydrogen gas to generate energy, it will gradually turn into a helium-filled planet.And so, it began to be destroyed.Core Sun becomes hotter.The size of this planet is 1.5 times higher and they will be twice as bright now.It continued this process for 700 million years, then gradually cooled down.At that time, looking up from Earth, the Sun was like an orange ball, suspended in the cloudy sky.

About 1.2 billion years later, the Sun loses a quarter of its weight and it changes its trajectory: Venus will return to the orbit of the Earth and Earth to be "fired" further.

Finally, the Sun is turned into a red planet, about 166 times larger than it is now.Venus and Mars will be brighter.On Earth, the mountain will be "melted", forming many large lava flows.The sun will cover half the sky.

Although the planets in the solar system may be extinguished, life in distant planets may arise.For example, life on the planet Europa, the moon of Jupiter.

When the Sun reaches its maximum size, its core temperature reaches 100 million degrees Celsius, and helium synthesis takes place.Helium's nucleus will quickly break down, releasing a lot of energy.At that time, the Sun gradually reduced its size.This process takes place over the next 100 million years.The results of the reaction process will produce new substances: oxygen and carbon.When these substances in the nucleus are large enough, the Sun is enlarged twice. After that, they turn back into helium planets, carbon and oxygen decompose but energy is still enough for it to continue . death.

The sun continued to swell when Helium and hydrogen gas were gone.It will be 180 times bigger now and 1,000 times brighter.A large amount of matter will be "thrown" into the universe and its weight will be lost.At that time, the planets in the solar system were only "memories".

The core is oxygen and carbon gas, surrounded by a thick layer of helium gas which makes the Sun unstable.It starts to react again, after every reaction the Sun loses a bit of weight.This process takes place until it is only inert, which is about the same size as the Earth.The Sun's core gradually cools and turns into a rocky planet.
