As soon as sunrise, the first thing we see is the star that dominates our solar system. The sun not only illuminates our planet, but is also the cause of the existence of meteorological phenomena and life on the planet. Many people have ever wondered what the temperature of the sun is. And it is that the sun is considered a massive source of nuclear energy that is located in the center of the solar system.
In this article we are going to tell you what the sun temperature, what characteristics does it have and what is its importance.
Key features
What we have not even measured heat is a massive source of nuclear energy that is located in the center of the solar system. It is regarded as a star. Its temperature is so high that it would be possible to just get close to it. Already from a distance the one that is to our planet from the sun can burn our skin and suffer serious cases of burns. The sun's rays penetrate our atmosphere although there are different filters that help reduce the ultraviolet radiation that reaches us. However, at such a distance it can already cause us damage.
There are people who have died from very long sun exposure and without protection. Therefore, you do not think about approaching the sun. It can lead to skin cancer and dehydration, among other diseases. This is one of the main reasons why planets may or may not harbor life. Depending on the position in which we are in the solar system with respect to the main star, we can have a temperature that remains a habitable environment. This makes planet earth considered as one of the planets entering the 'habitable zone'.
He not only warms us, allows the existence of meteorological phenomena and David to the planet, but also provides us with vitamins. Receiving sun exposure in small amounts provides us with great vitality to human beings and other living beings. The temperature of the sun depends on many factors. The temperature of the sun that we perceive depends a lot on the season of the year that we are, global warming, and other aspects such as the amount of greenhouse gases in the atmosphere.
What is the temperature of the sun
Our atmosphere has been affected by the action of the human being and the emission of polluting gases and it already has the same function as before. Since the sun is the largest celestial object in the solar system it has always been the subject of debate. As early as the XNUMXth century, scientists were able to reveal the temperature of the sun. This temperature is what indicates the surface of the sun. Obviously, inside the sun there will be a higher temperature.
For the measurement of the temperature of the sun if you used its bright and the distribution with respect to the wavelength of the visible spectrum. A temperature of around 6000 degrees Celsius was estimated, this being the most visible outer layer of the sun. The yellow color of this star is generated because of its high temperature. It is thought that if its temperature changes and increases it will turn a more blue color. On the other hand, if the temperature of the sun dropped, it would turn redder.
The sun has several layers just like there are layers of the Earth. The photosphere is that area that shows spots on its surface due to the existence of violent outbursts of energy. These eruptions are manifested in this area and are the ones that are generated through the large amount of energy retained from the sun. This energy comes from inside the sun. Pressure is the cause of nuclear reactions that take place inside the sun. These nuclear reactions take place thanks to the hydrogen nuclei that are sinking and forming helium nuclei. This is where nuclear fusion takes place.
For nuclear fusion to take place, there must be free hydrogen molecules, a large amount of pressure, and a high temperature. When these 3 variables occur, nuclear fusion occurs. These reactions cause the convection of a burst of energy across the surface of the sun. Heat and light are expelled by this bud. It is estimated that for every second there are about 700 million tons of hydrogen that are converted into helium ash. Pure energy of approximately 5 million tons comes out of this process.
One of the ways to measure the temperature of the sun is by measuring the amount of radiation reaching the Earth and using the distance and size of the sun to calculate it.
The importance of the photosphere in the temperature of the sun
The photosphere is the area that is responsible for measuring the visible light we receive from the sun. It is the densest area that has its atmosphere. Even though it can be seen quite dim, it is the coldest region of the sun. When we visualize this layer we can see a kind of disk like black dots that have been formed through strong eruptions of energy. In these areas is where a solar magnetic field is formed that is responsible for controlling all the activity of the sun.
From the center of the sun is where the very intense heat gushes out. The interior that is below the photosphere is where bubbles of hot matter are produced that create regions that are slightly shiny. To be able to interpret all these areas of the sun, temperature measurement methods have to be used. This is how we know that there are regions of the photosphere where brighter areas are created and other darker areas caused by cold plasma. This plasma is also generated from inside the sun.
Like our planet, there are convection currents in the sun, there is a pattern of movement that will cause these areas to be known as solar granulation. This solar granulation is responsible for distributing all the heat.
The internal sun temperature is 15 million degrees Celsius, while the external is 5.500 degrees Celsius.
I hope that with this information you can learn more about the temperature of the sun.
