The Moon, Earth's natural satellite, formed from debris after a massive collision with a Mars-sized body. This image illustrates its formation and key facts.
The Moon is Earth's only natural satellite, located about 384,000 km away, with a diameter of 3,474 km. It formed about 4.5 billion years ago from debris after a Mars-sized body collided with Earth. The Moon has no atmosphere and is covered in craters. Scientists believe it was formed from the debris of this collision. The image shows a diagram of the Moon with craters and a text description explaining its formation and characteristics.
