According to scientists, the sun was formed from a medium-sized nebula about 4.6 billion years ago.
73% hydrogen, 25% helium and the remaining 2%
Slowly center the star, which is made up of other gases
Eight planets are formed and begin orbiting the sun in specific orbits. Then satellites are formed around the planets and they revolve around their respective planets.
According to astronomers, the Earth was formed about 4.5 trillion years ago and is centered around the Sun at a speed of about 1670 km / h or 464 m / s. Rotating at speed. The earth also rotates from west to east on its own axis.
In this way, just as the planets in the solar system revolve around the Sun, so does the Sun revolve on its own axis, orbiting our Milky Way galaxy in its own orbit around the "Galactic Center".
This galactic center is basically the center of our Milky Way galaxy. And in the center of our galaxy is a huge 'supermassive black hole'. And because of the mass of this black hole, the sun revolves around its 'baricenter' or galactic center.
At the center of this galactic center is 220 km / s. It takes about 225 to 250 million years for the sun to revolve around the entire solar system at a single speed. This period of the Sun's rotation around the galactic center is called the "galactic year."
According to astronomers, the Sun has been able to revolve in its own orbit around the Galactic Center about 20-25 times since the Big Bang. This orbit of the Sun is fairly elliptical. In addition to the Sun, there are stars many times larger than the Sun in this Milky Way galaxy that orbit around the center of their own barrister or galactic center.
The Milky Way galaxy extends from the galactic center to about 100,000 light-years. However, the sun is fairly close to the center. Our Sun is about 27,200 light-years from the Galactic Center. The Milky Way galaxy looks a lot more spiral. Its arms spread around from the center. It also has many small arms. In fact, these arms are the 'light zone'. Our Sun is located near the smallest "Orion" region between the two main arms, Perseus and Sagittarius.
Every large cosmic object in this universe revolves around any other specific object as well as its own axis. Similarly, the sun revolves around its own axis once every 26 days. That is, 26 days of the earth is equal to 1 day of the sun.
In addition to revolving around itself, our Milky Way galaxy also revolves in the same way that the sun revolves in an elliptical path around the galactic center. Astronomers have also observed the rotation of our neighboring galaxy "Andromeda" from Earth. The rest of the billions of galaxies in the universe revolve according to cosmic rules.
And so the Sun revolves around the galactic center of our galaxy due to the mass of the supermassive black hole at the center of our Milky Way galaxy.
