What if Jupiter gained just a little bit more mass

of all the planets in the Solar System combined.

and is made up of the same elements as the Sun.

to initiate a fusion reaction in its core -

the necessary requirement to be accepted into the star club.

and crash them all into the one we have now,

we'd be able to build a second star in the Solar System.

But that star would be nothing like the Sun.

Jupiter would be massive enough to become a red dwarf -

As every red dwarf out there, it wouldn't be too bright.

is the most light that Jupiter could hope to spit out.

Because Jupiter is four times further away from us than the Sun,

the Earth wouldn't get much heat from it.

By and large, Jupiter turning into a red dwarf

wouldn't change anything for life on Earth.

A Jupiter-star would appear red and a bit brighter than the Moon at its full phase.

Would it at least have a gravitational impact on the Solar System?

The former gas giant would slightly shift the orbits of the other planets.

But not enough to set them on a collision course with one another,

or launch them out of their orbits into outer space.

from the asteroid belt that Jupiter might send towards the Earth.

We'd need to learn to detect and destroy them

Other than that, not much would change for the Solar System.

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,

and planets would change their orbital course.

It's hard to predict what would happen to Earth in this gravitational mess.

It could be anything from being pulled a little too close to Jupiter-star

to being left drifting alone in the void of space.

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

Maybe someday soon we'll get a closer look,

and send a manned spacecraft rushing inside the gas giant.
