What is the ultimate fate of a star similar in mass to our Sun?
Answer
It becomes a red giant, sheds layers to form a planetary nebula, leaving a white dwarf.
Stars similar in mass to the Sun become red giants, but they do not explode; instead, they drift away their outer layers to form a planetary nebula, leaving behind a cooling white dwarf.
