The sun is actually one of the stars. The heat of the sun is caused by the fusion reaction between hydrogen and helium that occurs continuously there. The heat on the outer surface, known as the crust, is less than on the inner surface. It is estimated that the heat can reach up to 6000° Celsius. Unless you're closer to the core which is many times hotter than the outside. And can make anything melt like iron. The distance is so far that we only feel a little of the heat of the sun from the earth. It is also blocked by layers of the atmosphere beyond Earth. However, the light is very useful.
Plants cannot live without that light. The darkness of the night is gone. Humans also need light for bone health. The oceans can even freeze without sunlight. And we will lose the spring. How much the sun plays a role in this life. Somehow if the sunlight can no longer be emitted. Has it ever crossed your mind if the earth passed far from its orbit. Even the light of other stars is not bright enough because they are so far away. Looks like seeing his condition now the sun's light will not go out. Like other stars that are known to have died.
Research continues to be carried out considering how important the sun is. Although the equipment we have is still very minimal. It could be that our sun is not the only one. But also we need more modern aircraft. To explore space further because the distance is very wide. The emptiness of oxygen there made it a place not to be approached. Maybe we need to take a closer look to find the exact science. The sun is really nothing behind the millions of stars out there. But because we live on earth.
And the sun is the center of the cycle. We really can't forget the sun. The theory is that the sun always stays where it is. Nothing should affect it other than other objects that pass nearby. And until now we have not found another heat source like the sun.
