   When will the Sun become a big star?

   • Right now, our Sun is in a stage called yellow dwarf. It is about 4.5 billion years old. In another 5 billion years the Sun will become a big, cool star called a red giant. A few billion years after that, it will become a small white dwarf star. It will shrink to around the same size as Earth, but it will weigh 20,000 times more.

   How long does a star last?

   • For a star the size of ours, this phase lasts a little over 8 billion years. Our solar system is just over 4.5 billion years old, so the sun is slightly more than halfway through its stable lifetime. After 8 billion years of happily burning hydrogen into helium are over, the sun’s life gets a little more interesting.

   How big is the Sun compared to other stars?

   • With a diameter of some 864,000 miles (1.39 million km), the Sun dwarfs any other object in our solar system. In fact, you could fit about 1.3 million Earths inside it. However, despite its dominance over our solar system, the Sun is still a relatively diminutive star when compared to others in the known universe.

   Is the Sun a star?

   • Our Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It’s about 93 million miles (150 million kilometers) from Earth and it’s our solar system’s only star. Without the Sun’s energy, life as we know it could not exist on our home planet.
