Answer:
Rigel
Explanation:
Rigel is the star that is both brighter and hotter than the sun. We know this because the higher the temperature, the hotter it is. While the sun is around 6,400 degrees, Rigel sits at around 20,000 degrees.
To know if it's brighter, we can see that the higher up the star is, the brighter it is. In the image, Rigel is higher up than the sun is.
