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:
