1. What is a stars ?
Stars is the large ball of the hot gas. The heat of the stars is made in the center by nuclear
fusion . The stars look small because along way aways from the sun. There are lots of different
color and sizes of stars. The star can be cool and dim,cool and bright,hot and dim and hot
and bright .They can be blue, red, and yellow,white and orange.
2.Type of the stars:There are 4 type of the stars Super Giant,Giant,Main Sequenece and white Dwarf. Super Giant stars are large middle age stars, they have medium temperature.
Also they are bright stars. Giant stars are large middle age stars. they are irregular range stars on temperature, luminosity and color.
3.The H-R Diagram:The Hertzsprung-Russel Diagram, is graphical tool used by astronomers to classify stars based on their luminosity, spectral type, color,temperature, and evolutionary stage.This diagram shows relationships and differences between stars.
4. Nuclear Fusion: A stars is like a gigantic nuclear fireplace. The nuclear reactions inside a stars change two hydrogen gas and molecules into a helium molecule .
5. The life cycle of a star: The stars come in many different shapes,size,and color,each of which signifies a different type and life cycle. All stars are born in the same manner-the begin as nebulae, clouds of dust,hydrogen,and helium . These clouds slowly candense as they age,forming small hot areas
of gas called protostars.
