Mars (and all the other planets and moons in our Solar System) are not luminous as in creating their own light. However, Mars reflects light from the Sun, a (luminous) star, making it look like it is creating its own light.
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.

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.
i think it is not luminous
No, it is not.
I think that asteroids are non-luminous
The earth is Non-luminous.
It's non-luminous
A TV, when it's on and showing an image is luminous. When it's off, it's non luminous.
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.
Correct. A planet is defined as orbiting a sun. The moon orbits the Earth - so it's a satellite. It doesn't shine under its own 'power' but reflects the light of the sun shining on its surface.It is a non-luminous object
A planet is a non luminous object revolving a star in space.
Mars has a magnetic field.
Jupiter is not luminous in that it emits light, it reflects the Suns light so that it is visible to us on Earth. See also Albedo.
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.

For the most part, no, Mars is not luminous. However, at certain angles, it can reflect light from the sun and be seen.
