The name of the natural satellite of the Earth is the Moon. The Moon is the fifth largest satellite in our solar system and is about 1/6th the size of Earth. It's approximately 238,855 miles (384,400 kilometers) away from our planet. The Moon has a significant influence on Earth, notably affecting ocean tides and contributing to the stability of Earth's axial tilt. Its surface features include craters, mountains, and flat plains known as maria. The Moon has been a subject of human exploration, with NASA's Apollo missions successfully landing astronauts on its surface in the 1960s and 1970s.
