It can be with the light it reflects from the sun, but not over long distances. Mars does not emit light except in the very long wavelengths (infra red). It is non-luminous. It is only visible because of the light it reflects, as the first answer states.
Mars is not luminous in the same way as stars or celestial objects that emit their own light. Mars appears bright in the night sky because it reflects sunlight, but it does not produce its own light like a star.
In the ordinary sense of the word, the planet Mercury is not "luminous", that is, it does not radiate visible light like the Sun does and we ordinarily see sunlight reflected from it's surface. However, like all bodies above absolute zero in temperature, Mercury radiates "black body radiation". Since Mercury is quite hot as planets go, it radiates more such radiation than most planets. This radiation is in the infrared spectrum though, so it is not "visible" to humans without artificial aids. See the link. When it comes to Hg, the element Mercury, the answer is pretty much the same except that Mercury vapor (in streetlights for example) IS luminous.

Luminous objects are those which can produce or give out light of their own, while non-luminous objects cannot produce or give out their own light. Some examples of luminous objects would be the sun, stars, fireflies, glowworms and some deep sea fish Some examples of non-luminous objects would be the planets Mercury, Venus, Earth, Mars,Jupiter, Saturn, Uranus, Neptune and also Moons.

Yes, that would be awesome.

Luminous.
Luminous could also mean 'full of light or illuminated'. For example: luminous hands of a clock. Here, luminous denotes shiny or that give light. In the example: luminous room; luminous indicates well-lighted. Something that is clear or easy to understand is also termed luminous. Fro example: luminous prose or luminous theory. Luminous could also mean inspiring, intelligent, or enlightened.
luminous is correct
If the bulb is switched off, then we would call it non-luminous.

Some tables may be painted with luminous paint. Most are not luminous.
