The celestial body that orbits around the Earth is the Moon. It is Earth's only natural satellite and is about 1/6th the size of Earth. The Moon's gravitational pull affects Earth's tides and plays a role in stabilizing the planet's axial tilt, which influences climate. The Moon goes through various phases, including the new moon, first quarter, full moon, and last quarter, as it orbits Earth approximately every 27.3 days. The Moon has captivated human interest for centuries, inspiring mythology, art, and scientific exploration, including the historic Apollo missions that landed humans on its surface.
