the Moon is often described as being shaped like a lemon. It's not a perfect sphere, but rather an oblate spheroid with a slight bulge on the side facing Earth and another on the opposite side. This shape is primarily due to the Moon's early formation and the influence of Earth's gravity. Here's a more detailed explanation: Tidal Forces: Shortly after the Moon formed, it was still hot and partially molten. Earth's powerful gravity exerted tidal forces, causing the Moon's shape to become elongated. This resulted in a bulge on the side facing Earth and another on the opposite side. Early Molten State: The Moon was not completely solid when these tidal forces acted on it. Its thin outer crust was floating on a molten core, allowing the tidal forces to deform the Moon's shape. Not a Perfect Sphere: Due to the early tidal forces and the Moon's internal structure, it never achieved a perfectly spherical shape. The bulges remain, making it more like a lemon than a ball.
