The nearest star to the Sun is alpha centauri. Actually it is not one but a group of three stars which is called triple star system Their names are proxima centauri, alpha centauri A and alpha centauri B. Which is located at a distance of 4.37 light years from the Sun Light year is the distance that light travels in one year. This distance is equal to 9,460,528,400,000 kilometers Just as the Earth revolves around the Sun, the Sun also orbits the Milky Way Galaxy along with the entire Solar System.
After the surface, the atmosphere of the Sun begins. In which there is chromosphere and corona But alas, we cannot see them because of the very strong brightness of the surface. But when a solar eclipse occurs, the moon covers the photosphere and we can easily see both these levels.
Now let me tell you about a special secret of this.The temperature starts increasing from the surface to the top. Where the surface is only 5,500 ℃ hot, the corona is as hot as 2 million ℃.
Why does this happen and what is its temperature?
Our Sun is the star around which the planets revolve. It is called Planetary System. A total of 8 planets revolve around the sun. Apart from this, dwarf planets, asteroids and comets also orbit it The closest planet to the Sun is Mercury and the farthest planet is Varuna The Earth rotates on its axis, when it is in front of the Sun.

it is day and when it is in the opposite direction, it is night When a planet completes one orbit around it, then it is called a year there one orbit around the planet Mercury
