q250 Posted November 28 Share Posted November 28 assume we have one gas giant very close to star. now assume that this giant has his own sputnik, call it sputnik 1, and this sputnik has his own sputnik, call it sputnik 2. question, is there exist orbits of sputnik 1 and 2 such that sputnik 2 is always in shadow? what about case with sputnik 3 in same logic, can it be always in shadow? what if we add several another sputniks to gas giant, will it help? either way main request find such orbiting body that it never touched by star light.

mateusviccari Posted December 17 Share Posted December 17 That's an interesting question, I'm not sure myself but I'd bet it's not possible, at least not with these settings (star, planet, moon, sub-moon) because the sub-moon would need to be located far enough from the parent moon for its orbital period to be long enough. The problem is that you cannot put a sub-moon that far because it would escape the moon's orbit and become itself another moon of the planet. This becomes an increasing issue the closer the moon is from its planet, limiting even further the maximum stable distance of the sub-moon from its moon.
