Jakarta –
Almost every day detikers will feel the heat from the Sun. The heat energy produced by the center of the solar system is very helpful for human life, for example drying clothes during the day so they dry quickly.
So, did you know that the Sun consists of various layers? If not, then read the complete explanation in this article.
Understanding the Sun
The sun is the largest source of energy for Earth. Quoting the book Integrated Science for SMP/MTs Class IX B by Agung Wijaya, the energy received by the Earth’s surface from the Sun is 25,000 times the energy received from within the Earth itself.
The solar energy emitted is in the form of electromagnetic waves. Next, these waves head towards Earth and will reach the upper surface of the Earth’s atmosphere, but only about 50% of the total energy from the Sun is absorbed by the Earth.
Solar energy entering the Earth is called insolation. The function of the Sun can radiate heat energy to land, oceans, and provide energy to creatures on Earth. This is because the Sun can produce its own light so it can produce heat energy.
Layers of the Sun
Reported by the Ministry of Education and Culture website, the Sun consists of four layers. What are the layers of the Sun from innermost to outermost? Check out the explanation below.
1. Core of the Sun
The innermost layer of the Sun is the Sun’s core. In this layer the temperature can reach 15 million Kelvin, so it is enough to maintain thermonuclear fusion which functions as a source of energy for the Sun. Later, the energy from the core layer will be radiated to the outer layers of the Sun and reach space.
2. Photosphere
The next layer of the Sun is the photosphere which is the deepest layer of the Sun that humans can observe directly. This layer is about 250 miles (400 km) above the Earth’s core.
The temperature in the photosphere layer varies quite widely, namely between around 62,000 degrees Celsius at the bottom and 3,700 degrees Celsius at the top. Then, the thickness of this layer is around 300 km.
Inside the photosphere are sunspots, which are areas with a strong magnetic field that are cold and darker than the surrounding areas.
3. Chromosphere
The chromosphere is the layer of the Sun that is between 250 miles (400 km) and 1,300 miles (2,100 km) above the photosphere. The temperature at the surface of the chromosphere also varies, namely around 3,700 degrees Celsius at the bottom (which is called the minimum temperature) and 7,700 degrees Celsius at the top.
The thickness of the chromosphere layer can reach 2,000 km. Uniquely, the chromosphere will look like a red ring surrounding the Moon during a total solar eclipse.
4. Crown
The corona is the outermost layer of the Sun which has a temperature of up to 50,000 degrees Celsius with a thickness of up to 700,000 km. The corona layer has a grayish color resulting from ionization of atoms due to very high temperatures.
The corona cannot be seen with the naked eye except during a total solar eclipse or using a coronagraph. During a total solar eclipse, at a glance the corona will look like a grayish crown surrounding the Moon.
That’s an explanation of the layers of the Sun. Hopefully this article can increase detikers’ knowledge.
