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 [tex]$E$[/tex] into a decimal number. Use your research to complete the chart.

\begin{tabular}{|c|c|c|c|}

To accurately complete the given chart with information about the six stars, let's provide the details in a structured format based on credible research findings. Here is the detailed, step-by-step solution:

1. Sun:
- Distance from Earth (light years): 0.000016038
- Luminosity in comparison to Sun: 1 (the Sun's Luminosity is the baseline and thus is 1)
- Surface Temperature (Kelvin): 5778 K

2. Alpha Centauri A:
- Distance from Earth (light years): 4.367 light years
- Luminosity in comparison to Sun: 1.5 times that of the Sun
- Surface Temperature (Kelvin): 5790 K

3. Sirius B:
- Distance from Earth (light years): 8.611 light years
- Luminosity in comparison to Sun: 0.00033333333 times that of the Sun
- Surface Temperature (Kelvin): 25200 K

4. Barnard's Star:
- Distance from Earth (light years): 5.978 light years
- Luminosity in comparison to Sun: 0.0004 times that of the Sun
- Surface Temperature (Kelvin): 3134 K

5. Sirius A:
- Distance from Earth (light years): 8.611 light years
- Luminosity in comparison to Sun: 25.4 times that of the Sun
- Surface Temperature (Kelvin): 9940 K

6. Proxima Centauri:
- Distance from Earth (light years): 4.246 light years
- Luminosity in comparison to Sun: 0.00005 times that of the Sun
- Surface Temperature (Kelvin): 3042 K

The completed chart is:
