During the first few million years of our sun’s lifetime it was surrounded by a protoplanetary disk made up of gas and dust. Jupiter coalesced from this disk and became encircled by its own disk of satellite-building material. This “circum-Jovian disk” was fed by material from the sun’s protoplanetary disk that rained down on Jupiter at the planet’s poles, and flowed back out of Jupiter’s gravitational influence along the planet’s equatorial plane. But this is where things get tricky for satellite formation; how did this ever-changing disk accumulate enough material to form moons?
