Is the moon a luminous object?

No

First of all, a luminous object is something that produces its own light. The moon does not produce its own light. The Sun radiates light which is reflected to the earth by the moon. This is why it looks bright; the moon is only a whitish ball of rock.

An example of a luminous object is the Sun.
Because the sun is shining on it.

Just like all of the objects in a dark room, you can't see them unless you shine a

flashlight on them. The flashlight that makes it possible for us to see anything in

the solar system is the sun.
