No, an object that reflects light is not considered luminous.

Here's why:

* Luminous objects are objects that produce their own light. Examples include the sun, a light bulb, or a firefly.

* Reflecting objects simply bounce light that falls on them. They do not create light themselves. Examples include the moon, a mirror, or a white wall.

So, while a reflecting object might appear bright due to the light it reflects, it doesn't actually generate the light itself. Therefore, it's not classified as luminous.
