What is the approximate temperature of the supergiant Betelgeuse? Which star on this diagram is the most similar to the Sun in luminosity and temperature?
Understand the Problem
The question is asking for two pieces of information derived from the H-R diagram: the approximate temperature of the supergiant Betelgeuse and which star on the diagram is the most similar to the Sun in terms of luminosity and temperature.
Answer
Betelgeuse: 3000 K; Similar star: Alpha Centauri A.
The final answer is: The approximate temperature of Betelgeuse is 3000 K. On the H-R diagram, the star most similar to the Sun in luminosity and temperature is likely Alpha Centauri A.
Answer for screen readers
The final answer is: The approximate temperature of Betelgeuse is 3000 K. On the H-R diagram, the star most similar to the Sun in luminosity and temperature is likely Alpha Centauri A.
More Information
Betelgeuse is a red supergiant, much cooler and larger than the Sun, which makes it unique on the H-R diagram. Alpha Centauri A is a star similar to the Sun, found on the main sequence in terms of both temperature and luminosity.
Tips
A common mistake is misidentifying other stars near the Sun's position on the diagram. Check both temperature and luminosity.
