Maybe a tangentially related question, what happens if you form a system very much like our solar system, but the central body never actually ignites and it just remains a dark ball of hydrogen. Would the system still be called a solar system?

That'd be more of a rogue planet with moons.

That's what i was thinking but if it's the size of our solar system and the 'moons' had moons it gets weird.

(But i guess our moon could have moons so it's moons all the way down)

Sometimes called moonmoons.

A system the size of our solar system centred on a jupiter-sized object wouldn't be very stable - it'd be quickly disrupted by an encounter with a star.
