A star’s color is most directly related to its The star closest to the Earth is Stars are formed out of Our Sun makes its energy from this reaction: The hottest stars are what color? Stars that seem to be arranged in a pattern are known as The biggest stars are called The Big Bang Theory is based on the assumption that The star Polaris is interesting because it is Magnitude refers to a star’s Which of the following objects make their own light? Planets, moons, stars, or satellites True or False Our sun has about 10 billion MORE years to live. It takes light from the sun about 8 _________ to reach the Earth.
