The celestial body that orbits the Earth is the Moon. It is Earth's only natural satellite and is the fifth largest moon in our solar system. The Moon significantly influences various phenomena on Earth, most notably the ocean tides due to its gravitational pull. Its surface features include craters, plains, and mountainous regions, and it has a synchronous rotation that keeps the same side facing Earth at all times. The Moon has been a focal point for human exploration, with Apollo missions landing astronauts on its surface between 1969 and 1972, marking significant achievements in space exploration.
