Moon - Page 19
The Moon is a natural satellite that orbits the Earth. It is the fifth-largest moon in the solar system and is the only celestial body beyond Earth that humans have visited. The Moon has a significant impact on Earth, influencing tides, various biological cycles, and the planet's climate. It is composed primarily of rock and is characterized by its surface features, including craters, mountains, and maria—vast basaltic plains formed by ancient volcanic eruptions. The Moon's gravitational pull affects the motion of Earth, and its phases have been used historically for timekeeping. It has no atmosphere, which means it experiences extreme temperature variations and is subject to the effects of space weather. The Moon is about 1/6th the size of Earth and is located approximately 384,400 kilometers (238,855 miles) away from it. Its cultural significance is immense, appearing in various myths, literature, and art across different civilizations.
