FAQs About the Moon
1. How far is the Moon from Earth?
The Moon is approximately 384,400 kilometers (238,855 miles) away from Earth.
2. Why does the Moon affect tides?
Its gravity pulls on Earth’s oceans, causing high and low tides.
3. How long does it take for the Moon to orbit Earth?
The Moon completes one orbit around Earth in about 27.3 days.
4. Who was the first human on the Moon?
Neil Armstrong became the first human to walk on the Moon in 1969.
5. Does the Moon have water?
Yes, water ice exists in permanently shadowed craters at the poles.
6. Why does the same side of the Moon always face Earth?
The Moon is tidally locked, so its rotation period matches its orbit around Earth.
