How did the sun come? We answer today on our site because life on Earth in all its forms depends on the light and heat sent by the sun. Since the regular flow of light and heat from the Sun plays fundamental and important aspects in the evolution and evolution of life, it is important to know how the Sun formed.
How was the sun formed?
- There are many scientists who believe and believe that the sun and the rest of the solar system formed regarding 4.6 billion years ago and that they were formed by a giant cloud of dust and gas, and this cloud is called by another name, the solar nebula.
- When the solar nebula collapsed due to its own gravitational force, many materials were pulled toward the center and the sun was formed in this way. The sun is an object that contains a large amount of nuclear fuel. This amount is quite enough for another five billion years.
- Then following those years the sun becomes a red giant, then this red giant sheds its outer layers, the core collapses, and the sun gradually fades and over time becomes a white dwarf and enters its final phase.
- This last stage will make the Sun a cold and faint object, in which case the Sun will be known as a black dwarf.
Solar Components
The sun contains more than sixty different elements, but there are many elements in the sun and it is considered one of the most important elements that make up the sun, which is hydrogen representing regarding 92% of atoms and helium representing regarding 7.8% of atoms.
Also, a small percentage of the other heavy elements are in the sun where nitrogen, carbon, silicon, and oxygen are.

Solar components from the inside
- Researchers have proven that the sun from the inside consists of six components, and the first of these components is the center of the sun or, as scientists say, the core or the core, and this core has a very high temperature.
- The radiation region surrounds the so-called convective region, which is a radiation region that attempts to store energy for a very long time, and a physical region surrounds the radiation region.
- Outside this region, we will find three layers of the solar atmosphere, and the layer closest to the heliosphere to the Sun is the photosphere, the layer that humans can see or see from the planet.
- The other two layers that we can’t see from Earth are the chromosphere and the corona.
After knowing how the sun was formed, it can be recognized: it is located in the center of the solar system… Learn all the information regarding the sun
nuclear fusion
- Nuclear fusion is a process that occurs inside the core of the sun, and this nuclear fusion is done by stimulating the temperature inside the core to regarding 15 million degrees Celsius, which leads to high pressure and temperature due to gravitational forces.
- Through this process, the hydrogen atoms are compressed and then combined to produce the element helium due to the high temperature, which causes the atoms to split into charged particles and in this way the gas will turn into a plasma.
- Later, the energy from the gamma rays and neutrinos will be transferred to the radiation zone, and these photons can be captured regarding a million years ago before they rise to the surface.
- The sun rises every day due to the process of nuclear fusion and the conversion of hydrogen gas into helium gas.

What are the properties of the sun?
The sun has many properties that we can never enumerate, but we will mention some of these properties, namely:
- It is a very massive star, the width of the Sun is regarding 1.4 million km, and if we consider the Sun an internally hollow sphere, then the Sun can contain more than a million planets.
- The sun is not a hollow sphere but a hollow star, but it is filled with a huge amount of burning gas, which represents regarding 98.8% of the total mass of the solar system.
- While the surface temperature of the Sun is very high at around 5500°C, the temperature at the center of the Sun has risen above 15.5 million°C.
- Several reactions occur in the core of the Sun that lead to nuclear fusion, in which case the hydrogen present will be converted into helium, which will generate the energy of the Sun.
- Scientists say that the solar surface is divided into three regions, the first region is the photosphere, which is the surface of the sun that is easy to see and is also the lowest layer of the atmosphere, the second region is the chromosphere, and the third region is the corona (solar corona).
- There are some sunspots on the surface of the sun, and these features are often cold and dark, these features are in the shape of a circle and occur when intense streaks of magnetic field lines within the sun project to the surface.
What is the importance of the sun?
The sun is a celestial body and is considered one of the most important stars in the Milky Way, and the sun has many benefits that we cannot live without and no one can imagine life on planet Earth without the sun, and it is one of the most important benefits that the sun provides. For planet Earth:
- The sun is the source of light energy and the only source of thermal energy for both humans and other living organisms, and we cannot imagine the existence of the Earth without sunlight or the heat of the sun.
- The sun supplies the human body with vitamin D, which is one of the most important vitamins one should take. If a person suffers from vitamin D deficiency, he will face many strenuous symptoms that make his life difficult.
- The sun’s rays provide all the plants with the energy they need for the plant to perform photosynthesis, and this process is converting the plant into other energy stored in the fruit using the energy emitted by the sun.
- While eating this fruit, humans benefit from the energy stored by the plant in the fruit as well as the vegetative animals which will benefit the carnivores. Therefore, the sun is an essential and important component of the food chain.
- Since the sun is constantly warming the oceans and seas, the sun is an important part of the planet’s water cycle, from which the water cycle will begin naturally.
- The sun gives the earth four seasons of the year as the planet revolves around the sun.
