Figure 1 is a simplified Hertzsprung-Russell (H-R) diagram showing the relationship between the luminosity and surface temperature of main sequence stars.

Luminosity is measured relative to the Sun (where the Sun has a value of 1).

A simplified Hertzsprung-Russell (H-R) diagram with Proxima Centauri plotted on the main sequence.

Estimate the surface temperature of the star Proxima Centauri using Figure 1.
