It's non-luminous
A TV, when it's on and showing an image is luminous. When it's off, it's non luminous.
The Earth is non-luminous, meaning it does not produce its own light. The light we see on Earth comes from sources such as the Sun, the Moon, and artificial lighting.
Some tables may be painted with luminous paint. Most are not luminous.
Luminous objects emit their own light, such as the sun or a light bulb, whereas non-luminous objects do not produce light but reflect light from other sources, like the moon or a table. Luminous objects are sources of light, while non-luminous objects only appear visible when light is shone upon them.
