The Moon That Disappears Every 79 Days | Our Solar System's Moons Iapetus

Journey 1.5 billion kilometres to Saturn's most bewildering moon: Iapetus. This world of stark contrasts features a divided landscape where light battles darkness, while a colossal mountain range encircles its equator, towering higher than Mount Everest. This celestial trickster defies explanation, vanishing before astronomers' eyes, only to reappear like cosmic sleight of hand. As we explore this enigmatic moon, what shocking truths about our solar system's violent birth might finally be revealed? ▀▀▀▀▀▀ Subscribe to our new channel!
