Inside this article you can learn about the composition of stars, what makes them shine, how long they last, and why they are so important to us. Topics such as degrees Kelvin, solar luminosity, and the fusion of hydrogen into helium are also discussed. Understand how stars shine. Realize the importance of stars. Discuss the differences.
Stars are massive bodies in space that are self-luminous.
This means that they can generate their own light. Stars are composed primarily of hydrogen, which undergoes a fusion process and becomes helium. This fusion of elements provides the energy for the self-luminosity. Planets are large objects in space that are composed of heavier elements such as carbon, iron, and oxygen. Planets do not provide light and none of the material on the planet undergoes fusion.
