 What is a star?
== A star is celestial body containing gas thus radiating energy in forms of light and heat. This ball of gas is held by its own gravity. This force is continually attempting to cause the star to collapse. This is the result of the pressure of hot gas and or radiation in the core of the star. This process is called hydrostatic support. == == @What composes a star? @Is the sun a star? @Is the sun a giant star? @How hot is the sun? @How do you know how old it is? @How do you know how hot it is? @How often do they die and be created?@Why can we see them? @What is light spectrum? @Why can we see rainbows? @How many are discovered and visible to the human eyes? @What are they named after? @What is a wavelength? @What is the closest and furthest star from planet earth? @What is the speed of light? @How is the energy source light and heat produced from it? @What is a supernova? @Why do they twinkle? @Why do stars shine? ==
