1. What is the diameter?3,474 km
2. What is the mean orbital distance?384,400 km
3. What is the Moon?The Moon is a rocky world that is Earth's closest neighbor. It lights up our night sky and is the only place outside Earth where humans have walked.
4. How did the Moon form?Scientists think the Moon was made when a Mars-sized planet called Theia collided with early Earth about 4.5 billion years ago. The impact threw out a lot of material that later stuck together to become the Moon.

Giant Impact Hypothesis: The leading theory suggesting the Moon formed from debris after a massive collision between early Earth and another celestial body.
Synchronous Rotation: The state where a celestial body's rotation period matches its orbital period, causing one side to perpetually face the primary body.
Regolith: A layer of loose, unconsolidated rocky material, dust, and soil covering the surface of a celestial body like the Moon.
Axial Tilt Stabilization: The Moon's gravitational influence preventing large, rapid variations in Earth's rotational axis angle, crucial for climate stability.
