8.6.2

Which of the following is the best answer to the question, "Will our sun become a black hole?"

• Our sun's mass is just right to create a black hole. As a high mass star, it will explode in a supernova and then collapse into a black hole.

• Our sun's mass is too high to create a black hole. As a high mass star, it will explode in a supernova and then become a white dwarf.

• Our sun's mass is too low to create a black hole. As a medium mass star, it will expand into a planetary nebula and then become a white dwarf.

• Our sun's mass is too low to create a black hole. As a low mass star, it will expand into a red giant and then collapse into a neutron star.
