      Our planet will be destroyed when our sun dies. The sun is a star, and stars have a life cycle too. When the sun dies, we will not have the correct atmosphere on Earth to survive.

      Our sun is expected to survive for another five billion years, though, so anything could happen to the human race before the sun goes out!

      I guess we don’t need to worry then – great answer Dawn!

      Dawn has the right answer, unless humanity manages to kill itself off before the 5 billion years is up.
