What would happen if Jupiter became a sun?
Things would get a lot more fun if Jupiter was replaced with a Sun-like star. If our gas giant became 1,000 times more massive, the Solar System would go wild. Asteroids would crash into planets, and planets would change their orbital course. Some of them might end up ejected from the Solar System altogether.
Could Jupiter become a second sun?
It may be the biggest planet in our Solar System but it would still need more mass to turn into a second Sun. Jupiter is often called a ‘failed star’ because, although it is mostly hydrogen like most normal stars, it is not massive enough to commence thermonuclear reactions in its core and thus become a ‘real star’.
Can Jupiter refuel the sun?
Well, about 90\% of Jupiter’s atmosphere is made of hydrogen. This makes it one big ball of fuel, even though it’s only 0.01\% the mass of the Sun. With four gas giants in our Solar System, we could keep the Sun sizzling for another 87 million years.
What will eventually happen to Jupiter?
Jupiter will continue to orbit the Sun as it evolves into a red giant. Although the solar wind will be much much more powerful, it won’t have a significant effect on the overall mass of Jupiter. When the Sun loses its outer layers it will, in the last million years or so of its life, lose about half its mass.
How long will Jupiter last?

Do we have second sun?
Our Sun may once have had a twin companion, astronomers have suggested – like the “binary” stars of Tattooine in Star Wars. Harvard researchers have said another sun was present as the solar system formed, and it could explain features including a cloud of debris at our solar system’s edge.
Can we refill the Sun?
The only fuel the Sun can use for fusion is in the core, which accounts for only 0.8\% of the Sun’s volume and 34\% of its mass. When it uses up that hydrogen in the core, it’ll blow off its outer layers into space and then shrink down into a white dwarf. One idea is that you could crash another star into the Sun.
