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.
