While a 'Giant' star may have a radius of up to 1,000 times that of Sol and be up to 100,000 times as luminous, most of the stars are in the 'main sequence' portion of their lifetimes and have values near the typical main sequence ones for their type. Sol, Earth���?�s sun, is a type G. Its spectrum, as filtered by Earth���?�s atmosphere, is the basis for standard illumination in Human quarters. | While a 'Giant' star may have a radius of up to 1,000 times that of Sol and be up to 100,000 times as luminous, most of the stars are in the 'main sequence' portion of their lifetimes and have values near the typical main sequence ones for their type.
