The Moon is so large relative to the Earth that it would be very difficult for Earth’s gravity to capture it as it moves past us. This is analogous to a human being trying to catch a bowling ball. A2. If a large object impacted on Earth and splattered debris into Earth orbit to form the Moon, most of the impactor’s core would fall to the center of Earth, leaving the Moon with a very small core. Most of the volatile metals (like gold and silver) would be vaporized, leaving the Moon deficient in those elements. A3. The co-accretion theory suggests the Moon formed as a separate object in close association with the forming Earth. That is, they formed at the same time and at the same distance from the sun. This theory fails to explain why the Moon s core is so much smaller than Earth s. It also fails to explain the more subtle differences in the chemical com
