Strictly speaking Mercury (the planet) isn't luminous, since that implies it has its own method of generating light. Astronomers speak of albedo, which is the ratio of light reflected as a fraction of incident light arriving on the body; the darker the body, the lower the albedo. Mercury has an albedo of about 0.1 which is roughly the same as our Moon - about ten percent of the light landing on it gets reflected back.

∙ 15y agoMercury is a planet; it does not glow on its own. It reflects the light of the Sun. Because Mercury is so close to the Sun, it is difficult to see because it is normally hidden in the Sun's glare.

Time it take for light to get to Mercury?
it takes about 3-4 minutes for light to travel to mercury
Is a lightning a source of light?
It is certainly a source of light but it is not a practical, usable source.
Does Mercury shine with its own light or reflected light from stars?
Mercury shines by reflecting light from just one single star: our Sun.
Can a rainbow form without the light of the sun?
No it is not a light source but a light trick a light source produces light
What is natural light sources?
The sun is an example of a natural light source. A source which gives of light that is natural (not made by electricity) is a natural light source.
Why is mercury used in streetlights?
The light emitted by excited mercury gas is predominantly in the visible spectrum and as a light source is relatively efficient.
How much light does planet Mercury get from the sun?
Well, light intensity is inversely proportional to the square of the distance from the light source. Based on the lengths of the semi-major axes of the orbits of Earth and Mercury, I figure the sunlight hitting Mercury is about 6.67 times as intense as the sunlight hitting Earth, disregarding what is filtered by our atmosphere, which is probably negligible.
Why doesn't mercury reflect to suns light?
Both mercury the metal and Mercury the planet reflect light quite well.
Is a traffic light a light reflector or light source?
light source
An object that gives out light is it a light source or it is a light energy?
It is a light source.
Time it take for light to get to Mercury?
it takes about 3-4 minutes for light to travel to mercury
What is a light source?
The Sun is a light source Something that makes light.
Is a computer screen a light source or a light reflector?
light source
Is a lightning a source of light?
It is certainly a source of light but it is not a practical, usable source.
Why Mercury vapours are used in Mercury vapor lamp?
Ionized mercury vapor radiates in the near ultra-violet (a high energy source of radiation) which energizes the fluorescent coating inside the bulbs.
What does Mercury do in a CFL?
Without the mercury in a CFL you wouldn't have light. The ballast in a CFL supplies initial current which excites the mercury which releases photons, or light. The mercury does not produce visible light, this happens only once the light passes through the phosphor coating on the inside of the bulb.
Why is candle a primary light source?
because its main source that gives it to light is one of the main source of light
