Without the moon in its regular orbit around the planet, would life exist on Earth? Or would the climate teeter between cataclysmic extremes? Today, the moon shines brightly in the night sky from about a quarter of a million miles away. When it first formed though, it was 15 times closer to Earth and its gravity had a tremendous influence on the planet. Slowly drifting further away from Earth, the moon has reshaped the world. It created seasons, the 24-hour day, tides and may have even influenced the evolution of life here on Earth.
