Do you mean lighter in color? Halley's comet has an albedo of about 0.04, which is the color of tar. Our Moon has an albedo of about 0.07, which is the color of weathered asphalt.
If you mean lighter as in less massive... we've never seen a comet as massive as our Moon, but there are some pretty tiny moons out there in the outer solar system; a few comets might be larger than some of them.
No. This becomes obvious specially when you take into account that all light coming from comets, is in fact a small percentage of reflected sunlight. Comets do not produce light. They reflect the light of the closest star. Under some circumstances a comet can seem brighter than the background stars.
luminous , it because they get closer to the sun , they warm up and eject gas and dust particles
no
no
The answer is not very specific; what threshold are you willing to accept as "bright"? Brighter than 1m? Brighter than 2m?
Because it's closer, like the moon
The Sun is bigger than some stars and smaller than others. It is brighter than some stars and dimmer than others. Relative to the Earth it is much closer than all other stars.
In absolute terms larger (more massive) stars shine more brightly than less massive ones. In relative terms (as seen from Earth) more distant stars appear dimmer than closer ones.
Gemini is a constellation, a pattern of stars in the sky. Most of the stars in Gemini are larger and brighter than the Sun, which is only of medium size and brightness.
Big stars are brighter than small stars, and hot stars are brighter than cool ones.
Quasars A+
Because they are closer or actually brighter.
It is better to say that the sun appears brighter because it is closer. Some stars are actually brighter than the sun.
Because it is nearer that the stars.
Stars differ with its shape.Also how are stars are brighter than others
Yes, the sun s brighter than most stars, but it is dimmer than most of the stars we can see with our naked eye.
The sun appears bigger and brighter than other stars because it is much closer to us than any other stars.
The sun only appears brighter than other stars because it is much closer to us.
moon is too nearer to earth than stars
The sky is brighter than the stars before it is dark.
Nubula does not exist.
