Question
The Hertzsprung-Russell diagram is a scatter plot of stars that show the relationship between stars’ absolute magnitude or luminosities against their temperatures. A researcher found out that the smaller the absolute magnitude, the brighter the star.

Based on the diagram, explain how will the Sun change from its current stage in the main sequence?

Explanation
Currently, the sun is at the main sequence stage, but in the next 5 billion years, the sun will expand and its position on the Hertzsprung-Russell diagram will change and move towards the upper right where the red giants live. At this position, the sun will have a smaller absolute magnitude, implying that it will be cooler and brighter.
