      A star is a huge ball of gas that’s hot and dense enough for nuclear fusion reactions to start happening inside it. Stars convert hydrogen to helium for most of their lives – that’s what the Sun is doing now – and as they get older they may make heavier elements like carbon and iron. All the heavy elements on Earth were made in stars that died before our solar system was formed!

      Stars are bodies of hot gas in space, that because of the amount of mass they have, they’re held together as a ball by their own gravity. They produce so much heat that they appear to be bright, and so though they are hundreds of thousands and millions of miles away we can see them in the dark of space.

      What Pumba says in the Lion King isn’t wrong 🙂

      stars are superheated gas balls that undergo nucleur fusion. They are mostly made of hydrogen and helium.

      I think the wikipedia article http://en.wikipedia.org/wiki/Star explains stars wa-ay better than I can…
