Jakarta –
Have you ever wondered, how hot is the temperature from the center of our solar system, namely the sun?
The sun has a radius of 696,342 km. That is, with such a size even the planet Earth as much as 1.3 million can be accommodated in it.
Then where does the heat generated by the sun come from? The sun’s heat actually comes from the planet’s core which is capable of carrying out thermonuclear reactions.
How Hot Is the Sun?
The sun has a temperature of about 15 million degrees Celsius which is equivalent to 27 million degrees Fahrenheit in the planet’s core. Meanwhile, on its surface area, the Sun has a temperature of 5,500 degrees Celsius or 9,932 degrees Fahrenheit.
Then the outer atmosphere that surrounds the Sun has a temperature of about 2 million degrees Celsius or 3.6 million degrees Fahrenheit. However, in certain areas there are temperatures of 20 million degrees Celsius or around 36 million degrees Fahrenheit.
The core of our Sun is indeed hot enough for a thermonuclear reaction. Scientists are still not sure about the reason for the high temperature of the sun’s atmosphere.
Some argue that it may be caused by energy moving through the sun’s magnetic field into the atmosphere where it exploded.
The temperature of the sun is measured according to theory supported by missions to the Sun, including NASA’s Parker Solar Probe. This mission is still in the task of uncovering why the corona (the atmosphere around the Sun) can be so hot.
Why Can the Sun Be So Hot?
The sun can be so hot due to the great pressure on its core and it creates continuous nuclear melting. From this thermonuclear reaction, heat, light, and energy will be created that radiate outward to the surface of the sun, the atmosphere, and into outer space.
Basically, the Sun is a giant ball of gas with 92% of the gas containing hydrogen. The great gravity and pressure at its core makes the hydrogen gas atoms collide with each other and creates the element helium.
This event is known as nuclear melting. From this smelting, a large source of heat energy is created, especially for our solar system.
Is There Hotter Than The Sun?
So far the hottest star besides the Sun is WR 102. This star is found in the constellation Sagittarius which has a surface temperature of more than 200,000 degrees Celsius or 360,032 degrees Fahrenheit. So the star has a temperature 36 times hotter than the sun.
Not only is WR 102 hotter than the Sun, because there are several other stars that also have high temperatures, such as white dwarfs and neutron stars.
How to Know the Temperature of the Sun?
The temperature of the sun is measured using theory and related tools, including using the Parker Solar Probe. In addition, scientists measure the temperature of the sun’s heat using a remote telescope with combined spectroscopic data.
The data that has been collected starting from measurements of the sun’s photosphere, chromosphere, transition region, and coronal atmosphere can be used as a source of information for scientists about the sun’s heat from the core to the surface. Basically, measurements of the temperature of the sun’s core can be determined mathematically and supported by other real-world data.
Real data can be gathered by studying the wavelengths of the sun. The color of the emitted light can be used to determine its temperature through the incoming spectrograph and divides the light into several components.
