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.

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.

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.
