What if we refueled the sun with all the gas giants?

Answer 1

If we refueled the sun with all the gas giants, the sun will continue to exist for an extra 200 million years. If we refuel the sun with only Jupiter, the sun will continue to exist for an extra 100 million years. However, Jupiter is important because it draws in many asteroids to protect the earth, so earth would get hit by much more asteroids. It's a tradeoff because we'll have less concern of the sun's death, but we'll have more concern of asteroids.
