For billions of years, the Moon has been our ever-present companion, influencing our culture and science, directing tides, and illuminating the night sky. What if Earth had two moons instead of just one? What effects might this change in the sky have on life, our planet, and even human imagination? A fascinating look at how a second moon might change our world, this thought experiment offers a window into physics, mythology, and astronomy. The Moon: Our Only Natural Satellite Before diving into the “what if,” it’s important to understand why having a single large moon is unique for Earth. Our Moon is unusually big relative to Earth, about one-quarter its diameter. This size influences Earth’s tides, axial stability, and even the length of our days. Most planets have multiple moons—Jupiter boasts over 90! Yet, Earth’s solitary, sizeable Moon is a key player in making our planet hospitable. What Would Two Moons Look Like?
