It is rather hard for us to realize that our sun is merely just another star in the sky. This is probably because we think of the stars as looking so tiny. The sun looks larger than any star because it is only about a million miles from the earth. The nearest star is 25 billion miles away!
What is the temperature on the surface of the sun? Scientists believe that it is about 6,0(D degrees Centigrade. To give you an idea of how hot this is, white-hot molten iron ased in making steel reaches a tempera- ture of about 1,430 degrees. So you sec how much hotter the sun’s surface is. And as for the interior of the sun, astronomers estimate it may be as hot as 20,000,000 degrees Centigrade.
Remember, scientists, arc only making a “guess” about this, because we know almost nothing about the interior of the sun. We do know something about the composition of this star. For example, it has been learned that the sun contains more than 60 of the chemical elements present in the earth. But it is hard to study the sun’s interior because the sun is surrounded by four layers of gaseous matter.
Is The Sun Hotter Than Lava?
Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can’t hold a candle to the sun!
