a’la 2010, would any moons that survive then be considered ‘planets’ ?

    If memory serves, 2010 ignited Jupiter by crashing Saturn into it. But you’d actually need about 250 Saturns (or 85 Jupiters) worth of hydrogen to get the job done. A lot of the moons would be within that new super gas giant’s roche limit even before fusion began.

      in the movie the weird black rectangles started appearing in jupiters atmosphere. it might have had something to do with the aliens creating a sun for europa, which had some kind of organic life on it

    Im pretty sure none of Jupiters moons would survive. But I suppose if they did perhaps they would change classification from moon to planet, but I think planet classification now also depends on size, so depending on size they still may not qualify. I don’t know if any of Jupiter’s moons are larger thaan Pluto, Ceres, etc.

      Why wouldn’t they survive? I think even if Jupiter gained enough mass to start fusion, it would not become significantly larger. It would just become more dense.

        The moons would almost certainly fall into Jupiter or be thrown from its orbit if itsuddenly gained enough mass to become a star.

          I assumed in this scenario that orbits would be left unchanged aside from orbital velocity - if we can magic Jupiter much bigger, we can magic the orbits too :P

        They’re in an orbit that works with jupiters current mass. If Jupiter gained enough mass to trigger fusion then I would think that many of them would with fall in or be slung out of orbit.

        I’d be interested to see if anybody has done the math though to see how that would all play out.
