Question 8 increasing temperature surface temperature (Kelvin) decreasing temperature You are looking at a cluster of stars that all formed at about the same time. When you compute the average color of the cluster, you find that the most common star is about five times larger (in radius) than our Sun, more luminous, and a different color. Using the HR diagram above, what is the average color of the cluster, and how old is it?
