WebMar 22, 2024 · The Moon was likely formed after a Mars-sized body collided with Earth. Earth's Moon is the fifth largest of the 200+ moons orbiting planets in our solar system. Earth's only natural satellite is simply called "the Moon" because people didn't know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in 1610. The Moon is a very slightly scalene ellipsoid due to tidal stretching, with its long axis displaced 30° from facing the Earth, due to gravitational anomalies from impact basins. Its shape is more elongated than current tidal forces can account for. This 'fossil bulge' indicates that the Moon solidified when it orbited at half its current distance to the Earth, and that it is now too cold for its shape to adjust … WebThe moon diameter is always 2,159 miles (3,474 km), which is 27% of Earth's diameter of 7,901 miles (12,715.43 km) at the poles.
