The Moon never changes shape: it is always a sphere. So why does it look different?
☀️ It has no light of its own
The Moon is lit by the Sun, like a ball in front of a lamp. We can only see the lit part.
🔄 It orbits the Earth
It takes about 1 month to complete one orbit. Depending on its position, we see all, half, or none of its lit side.
🌑🌒🌓🌔🌕
New moon → first crescent → first quarter → full moon → and we start over in the other direction.
🔦 Experiment: in the dark, with a fixed lamp and a ball at the end of your arm: slowly turn around and observe the lit part. You have just recreated the phases! Our packs
