The lifetime of a typical star (like our Sun) appears to be:
A)a few thousands of years.
B)a few millions of years.

D)essentially infinite because we know of no mechanism that can terminate the nuclear processes in a star's interior.

Question

Quizplus · Accepted Answer

The lifetime of a typical star like our Sun is expected to last for a few billion years. This is due to the slow burn of hydrogen fuel in the core of the star, which releases energy through nuclear fusion. As the hydrogen is depleted, the star will eventually evolve and either become a red giant or a white dwarf, depending on its mass. However, it should be noted that more massive stars have shorter lifetimes and may only live for a few million years.
