The distance between Earth and its moon is 3.84 × 10^8 meters, which is approximately 384,000 kilometers, reflecting the radius of the Moon's orbit around Earth.
To find the distance between Earth and its moon using the given information, we can refer to the radius of the Moon's orbit around the Earth, which is given as 3.84 × 10^8 meters (384,000 kilometers). This is the distance from the center of the Earth to the center of the Moon, and this value falls within the provided answer choices. Therefore, considering the other numerical values and our understanding of the Earth-Moon system, we can determine the final answer.
