What if Jupiter was a brown star?

we would be affected?
its gravitational force will be higher?
life would hold its moons? and mars?

Bumping for interest

It would be easier to spot at night, might even be able to see it during the day.
Not sure what would happen to its moons, I think it would be too massive to keep close orbits around it, eating them up.

How is the lifespan of a red dwarf so fucking long? You could build a giant space-base around one and live off it's energy forever.

>ultra cool
hella rad jupiter

Jupiter is big. But would need to be much bigger to be considered a brown dwarf, at least twice Jupiter's mass. Jupiter could in theory be ignited as a fusion powered star but would need help for that. A brown dwarf would be much easier to achieve ignition even though it is still too small to become an ignited star naturally but capable of nuclear ignition potentially..
Jupiter is a mini solar system in itself and could provide some sort of illumination for the moons in its orbit along with our sun, so at least there is potentially that.

I imagine those ultra cool brown dwarves would be perfect environments for life.

because they burn slow and not very hot, it's like the Prius of stars

It uses it's fuel very very slowly.

The age of white dwarfs is fucking mindblowing

Because they burn slowly and convection processes still occur within red dwarfs that don't occur in bigger stars. This convection continuously refills the stars hydrogen content in the core.
