Sun's red giant phase
WebRed giants can become so large that if we were to replace the Sun with one of them, its outer atmosphere would extend to the orbit of Mars or even beyond ( Figure 22.4 ). This is the next stage in the life of a star as it moves (to continue our analogy to human lives) from its long period of “youth” and “adulthood” to “old age.” WebSep 17, 2024 · A red giant is a star in its death stages.
