The fifth largest moon in the solar system, earth's moon is the only place beyond Earth where humans have set foot. The brightest and largest object in the night sky, the moon makes earth a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years. The earth and moon are tidally locked and their rotations are so in sync we only see one side of the Moon. Humans didn't see the lunar far side until a Soviet spacecraft flew past in 1959. The moon, located at an average distance of 384,400km from earth, continues to be a never-ending fascination for humans. NASA currently has three robotic spacecraft exploring the Moon – Lunar Reconnaissance Orbiter and the twin Artemis spacecraft. There is a new Artemis program to send astronauts back to the moon.
