(单词翻译:单击)
Although the sun is over one million kilometres away from us, we still feel its heat. In this sense, we can say that the sun is a very big fire ball.
The temperature on the surface of the sun is 6,000'C. The temperature is much higher deep inside the sun. If we could take a small piece of stuff1 from the centre of the sun, dozens of cities would be burned down. This gives you an idea of how hot the sun is.
