For no sooner has the sun risen with a burning heat than it withers the grass; its flower falls, and its beautiful appearance perishes. So the rich man also will fade away in his pursuits. (James 1:11)
1 Corinthians 15:41
The sun is not too hot or too cold when compared to other stars. Typically, there is a range of temperatures for stars. Blue ones are much hotter, and red ones are much cooler. The surface temperature of the sun is about 10,000° Fahrenheit (or 5505° Celsius and 5778° Kelvin [K]).
The coolest stars (under 3500°K) are red. Next on the scale are red-to-orange stars, with a temperature of 3500–5000°K. Then there are yellow-to-white stars, which range from 5000–6000°K. This is where our sun would be, since it has an average surface temperature of 5778°K. Next are stars in the white-to-blue range, with temperatures of 6000°K–7500°K.
Blue stars are the hottest (typically over 7500°K) and have three classes: A, B, and O. “A” contains temperatures above 7500°K, “B” contains temperatures over 11,000°K, and O contains temperatures over 25,000°K. The hotter the stars are, the more light they give off (known as luminosity).
Blue stars are a problem for those who believe in millions of years. Blue stars give off so much energy and burn their fuel so fast that they should not be able to last for long periods of time. But a recent creation of about 6,000 years helps to make sense of blue stars.
