How much larger would Jupiter have to be to begin fusion and become a star?

But although Jupiter is large as planets go, it would need to be about 75 times its current mass to ignite nuclear fusion in its core and become a star. Astronomers have found other stars orbited by planets with masses far greater than Jupiter’s.

How big does a planet have to be to become a star?

The simple answer is that a large planet is anything too small to be a star. The usual definition for a star is that it must be large enough to fuse hydrogen into helium in its core. A main-sequence star is one in which the heat and pressure generated by fusion are balanced by the gravitational weight of the star.

What if Jupiter was 1000 times bigger?

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. In the real world, Jupiter is forever destined to be a planet.

Are planets failed stars?

“Nearly all scientists who study the formation of planets believe that Jupiter formed in a very different manner than stars form, so that calling Jupiter a ‘failed star’ is misleading. Stars form directly from the collapse of dense clouds of interstellar gas and dust.

Can a planet become a black hole?

If a black hole were to form from the Earth itself, it would create an event horizon just 1.7 centimeters in diameter. If, somehow, the electromagnetic and quantum forces holding the Earth up against gravitational collapse were turned off, Earth would quickly become a black hole.

Will Jupiter ever become habitable?

While planet Jupiter is an unlikely place for living things to take hold, the same is not true of some of its many moons. Europa is one of the likeliest places to find life elsewhere in our solar system. There is evidence of a vast ocean just beneath its icy crust, where life could possibly be supported.

What if Jupiter hit the Sun?

As Jupiter made its way to the sun, it would disrupt the orbits of all the other planets, and possibly destroy them, as well as the asteroid belt.
