I have a vague recollection from the past that Jupiter is a "failed star" in that it is "close" to the mass required to begin fusion, so I was confused about how an exoplanet could have several times its mass and not be a star.
Turns out, the threshold for deuterium fusion is about 13x the mass of Jupiter, so I guess it's "close" in that it's closer than anything else in the solar system (other than the sun), but less close than I assumed. Still, Epsilon Indi Ab is even closer to becoming a brown star. Or perhaps a golden star? Because of the pee smell?
And lest you think this planet is niche or dorky, according to science:
So cool 😎
Since brown dwarfs are considered to be failed stars, Jupiter would be a "failed failed star".
God Jupiter, get your shit together.
Actually if Jupiter did get its shit together enough to start fusion I bet that would be a catastrophic event for earth so, sorry for being mean, Jupiter, thanks for tanking most of the asteroids for us, keep doing your thing, I think your red spot is very avant-garde.
But you repeat yourself
Apparently Jupiter's gravity well can work both ways, either stopping asteroids from reaching us or giving them just enough energy to reach us. It's quite impartial at that. This video from Braintruffle covers the gravitational dynamics: https://youtu.be/1zu41rrc_Ng
Jupiter you tricky minx
