Deneb is ~1000 pc away from us. Its flux $F_{Deneb} = 5 \times 10^{-12} F_{sun}$, where $F_{sun}$ is the flux from the Sun. What do its distance and flux imply about its luminosity $L_{Deneb}$ compared to the Sun's luminosity $L_{sun}$? (Hint: 1 pc $\approx$ 200,000 AU. $F = L/(4\pi r^2)$) Select one: a. $L_{Deneb} \approx 200 \ L_{sun}$. b. $L_{Deneb} \approx 2000 \ L_{sun}$. c. $L_{Deneb} \approx 200,000 \ L_{sun}$. d. $L_{Deneb} \approx 20,000 \ L_{sun}$.
