Yes, the sun is also a star. The light of the sun is burning with water and the light is its own light. Many of us think that the sun has so much energy that the sun must be bigger in size than other stars. But in the end it is not big. Everything else is much larger than its sun. But the reason we see the sun bigger than the stars is because the sun is closer to us. This makes the sun look bigger in size. Otherwise they are located far away. Because of this, some of them cannot be seen and some of them are too small to be seen.
