Uranus and Neptune might have swapped places a long time ago! Scientists believe that in the early days of our solar system, these two icy giants switched orbits. This theory comes from computer simulations that show a swap would make the current arrangement of the planets make more sense. It’s pretty wild to think about these massive planets playing a cosmic game of musical chairs. Space is full of surprises, isn’t it?
