Temperaturen p\u00e5 dens overflade er omkring 5 500 grader Celsius \u2013 mere end 20 gange varmere end en ovn p\u00e5 h\u00f8jeste temperatur. I centrum stiger temperaturen til omkring 15 millioner grader Celsius, og gassen er sammenpresset til en t\u00e6thed, der er omkring 10 gange st\u00f8rre end blys.<\/p>\n<\/div>\n<p>Ved s\u00e5 h\u00f8je temperaturer og tryk fungerer Solen som en atomreaktor, hvor brint omdannes til helium. Samtidig dannes der enorme m\u00e6ngder str\u00e5ling. Denne str\u00e5ling n\u00e5r frem til overfladen i form af synligt lys, infrar\u00f8dt og ultraviolet lys samt r\u00f8ntgenstr\u00e5ler.<\/p>\n<p>Hver time udst\u00f8der Solen en milliard ton gas ud i rummet med en hastighed p\u00e5 op til 2 millioner km i timen.
