Part A The chart below lists six stars. Research the luminosity, distance from Earth, and surface temperature of

each star. Make sure to research credible sites, such as nasa. gov, to complete your chart. Distances

should be given in light years and temperatures given in Kelvin, Luminosity (L) is how bright something is

in human eyesight. As you conduct your research, look for the luminosity of each star relative to the Sun

(Therefore, the luminosity of the Sun is 1), If your sources give a fraction for luminosity, convert the

fraction into a decimal

number. Use your research to complete the chart,
