Earth's only natural satellite is the Moon. It is the fifth-largest moon in the solar system and plays a significant role in various natural phenomena on Earth, such as ocean tides, which are influenced by the Moon's gravitational pull. The Moon is approximately one-quarter the size of Earth and is about 238,855 miles away from our planet. It has a significant cultural and scientific heritage, inspiring countless myths, legends, and works of art. The Moon has been the focus of human exploration, including the historic Apollo missions, leading to advances in our understanding of space and planetary science.
