The Sun Is The Center Of The Solar System, These Are Amazing Facts About It

The Sun is the center of the solar system. After reading the article about what you need to know about the universe, it means you already know that the Sun is one of the billions of stars in the universe.

Thus, it can also be concluded that the Sun is the closest star to Earth. The place where we live.

The Sun Is the Center of the Solar System and Some Amazing Facts

The Sun, the center of the solar system, turns out to be just a tiny star in the universe. This remarkable fact is nothing compared to the following facts about the Sun.

1. Formation of the Sun

The process of forming the Sun is the result of the gravitational decay of a region in a giant molecular cloud. The majority of the material gathers in the center, and the rest changes shape to become flat like a disk. Later, this disk becomes the solar system.

The material in the middle or center becomes hotter and denser, then the thermonuclear fusion process begins. This process is thought to occur in almost all stars. The method of forming the Sun occurred around 4.6 billion years ago.

2. Shape of the Sun

The shape of the Sun itself is almost round, consisting of a magnetic field and hot plasma. Plasma is a form of gas-like substance with ionized particles.

Three-quarters of the Sun's mass is hydrogen, while the other quarter is dominated by helium with several heavy elements such as oxygen, carbon, neon, and iron.

Unlike rocky planets, the Sun has no clear boundaries. It's just that the further away from the Sun's core, the gas density decreases, especially in the outermost part.

3. Sun distance

The distance from the Earth to the Sun is often called an Astronomical Unit or AU, so 1 AU is the distance equivalent to the distance from the Sun to the Earth. If in units of kilometers, 1 AU is equal to 149,600,000 kilometers.

Because of the Earth's revolution about the Sun, there is a closest distance and a furthest distance between the two. The most relative distance is called Perihelion, which is 147 million kilometers. Meanwhile, the farthest distance between the Earth and the Sun is called Aphelion, which is 152 million kilometers.

An even more astonishing fact is that another star that is closest to the Sun is called Proxima Centauri. The distance is 39.9 billion kilometers, or the equivalent of 270 thousand times the distance from the Sun to Earth.

4. Movement of the Sun

Another fantastic fact about the Sun as the center of the solar system is that this object also moves. The Sun, as the center of the solar system, is not stationary.

The Sun has a rotational movement on its axis. The action takes about 24 to 31 days to complete one complete rotation. The Sun also makes a revolution.

The revolution of the Sun is followed by all parts of the solar system, where the process moves around the center of the Milky Way galaxy. The Sun and all aspects of the solar system take 230 million years to make one complete rotation around the center of the Milky Way galaxy.

The Sun is the center of the solar system, which has fantastic facts. These facts are, of course, known through observations, research, and exploration of the Sun carried out by scientists.
