Is the sun a star or a planet?

The sun
Our luminary contains many secrets. To find the answer to the question “The sun is a star or a planet,” you first need to figure out how the planets and stars form and what they are.

How stars appear

Stars are incredibly huge accumulations of gas held by the force of their own gravity. In their bowels there are reactions of thermonuclear synthesis, as a result of which colossal energy is released. The first stars appeared at the dawn of the universe from clouds of gas and dust particles. These particles collided, forming large and large objects. And the larger the object became, the stronger it attracted new particles.

Such embryos of future stars warmed up from the constant bombardment of dust and larger pieces of matter. As a result, their gravity gathered around itself a cloud of gases, warming it up. Then the first thermonuclear reaction took place, and the star began to “shine”! The remaining gases and dust formed a disk around the young star.

How the planets appear

After the birth of a star, there are many “building materials” around it. This gas-dust disk rotates, carried away by the force of its gravity. All new and new particles of dust in it collide, creating larger objects. From constant collisions they warm up. Therefore, the first planets resembled volcanic lava, which gradually cooled, covered with bark of stone. Others gathered around themselves clouds of gas, becoming gas giants.

When the solar system only appeared, there were several dozen planets in it. They circled in a mad dance around their star, colliding, collapsing or merging. Small fragments attracted larger ones, becoming a part of them. Others flew to the periphery of the system, forming a belt of asteroids, existing, to this day. And all that is left inside this belt, attracted by the planets.

What is the Sun?

Now we have found out that our Sun belongs to the stars. But what is our luminary and what is its composition?

The sun consists mainly of hydrogen and helium. It contains other substances, but in much smaller quantities. There is at it a nucleus in which thermonuclear reactions proceed. Because of the incredible gravity, a photon from the core of the Sun reaches its surface for hundreds of thousands of years. Sometimes this path takes millions of years. After that, the photon needs only 8 minutes to get to the Earth. Every day we see the light formed in the bowels of the Sun hundreds of thousands of years ago.

The temperatures of the surface and the core of the star differ by several million degrees. The outer shell of the Sun is a crown, it consists of energy eruptions and prominences. Too strong eruptions send the flow of electrons, protons, neutrinos and other particles towards the Earth . When interacting with the magnetic field of our planet, they create one of the most beautiful spectacles – the northern lights!

The sun is an amazing heavenly body. It gives light to each of us. Everything in the solar system, including our planet and ourselves, consists of those particles of gas and dust that formed it. However, on the scale of the universe, the Sun is only a small star, the Yellow Dwarf, but which is native and close to each person!
