Part 1:

  1. What are stars made from?

They are made from very hot gases namely helium and hydrogen which are the largest elements. Many of them have smaller amounts of heavier rudiments such as carbon-oxygen, nitrogen as well as iron.

They seem to be in motion from east to west as a result of the earth’s rotation from west to east on its axis around the sun (Plummer & Krajcik, 2010).
