What if Jupiter was 80 times it's mass?

[00:00:00]Increase Jupiter's mass by 80 times to turn it into a star. All right, let's increase Jupiter's mass by 80 times, enough to trigger nuclear fusion.

[00:00:08]Jupiter becomes a red dwarf star. The increased gravity pulls the largest moons inward and flings the outer moons into wild orbits. You would think a second star would cook [music] Earth, but this small red dwarf barely warms us. The main problem would be gravity.

[00:00:23]Now we are in a binary star system where the new star and the sun orbits around a common point causing all planets [music] orbits to shift and rocks from the asteroid belt to get launched toward Earth. For months each year, the red star would light our night [music] sky.

[00:00:38]There wouldn't be total darkness, just red twilight. Other months the red star [music] is behind the sun and nights are normal. Earth's orbit becomes unstable.

[00:00:47]Some years [music] swinging farther from the sun, some years closer. There would be ice ages followed by brutal heat waves. Earth's stable climate would be gone.
