Here's a breakdown:
* The Moon is a large, rocky body: It doesn't have its own source of light like the sun does.
* Sunlight hits the Moon's surface: This light is then scattered and reflected in all directions.
* We see the reflected light: This is what makes the moon appear luminous to us.
Think of it like a mirror reflecting sunlight. The mirror itself isn't producing light, but we see the reflected light from the sun. The same goes for the moon.
Therefore, the moon is non-luminous because it doesn't create its own light. It's only reflective and shines because of the sunlight bouncing off its surface.
