What If Every Moon Became an Earth?

What if every moon in the Solar System was replaced with an Earth-sized planet? 🌍🌕🪐 In this incredible Universe Sandbox simulation, every natural satellite—from Earth's Moon to the giant moons of Jupiter and Saturn—is replaced by a full-sized Earth. How would these massive new worlds affect their planets? Would their orbits remain stable, or would the Solar System descend into chaos? 🌍 Earth Replacements: 🌍 Earth's Moon → Earth 🌍 Phobos & Deimos → Earths 🌍 Io, Europa, Ganymede & Callisto → Earths 🌍 Titan, Enceladus & Saturn's major moons → Earths 🌍 Uranus' major moons → Earths 🌍 Triton and Neptune's moons → Earths Every giant moon becomes a habitable-sized world, dramatically changing the balance of gravity throughout the Solar System. In this simulation, you'll see: 🌍 Every moon transformed into a planet the size of Earth 🪐 How the gas giants react to their massive new satellites 💥 Orbital instabilities, close encounters, and planetary collisions 🌌 The changing appearance of the Solar System 🚀 Which planets can keep their new Earth-sized moons ⚠️ Whether the Solar System remains stable or falls into complete chaos Watch one of the most extreme "What If" scenarios ever created in Universe Sandbox and discover what would happen if Earth-sized worlds replaced every moon in our Solar System!
