I dont have a specific question..its just im doing a project and really need help on knowing as much as i can about:

moon
stars
light pollution
moon light

the question for my project is..Do moon phases effect how many stars you see at night?..which..includes if the moon gives off light..what would happen to the stars

both give light

There is no moonlight, there is Reflected Light on the Moons Surface. The reflected light affects the pupil in the eye and either lessens or improves the naked eyes ability to see faint objects such as stars.
If a city has 80million Candle Power of Night Lights the distant stars can be obscured by the unnatural light pollution.
That is the difference between the Moon Reflected Light and Man Made Light, both are a form of Light Pollution, but one can be turned off by timeing to view distant objects better.
That is called a Lunar Cycle.

First off, the Moon does not give off light of its own. Rather, it reflects the light of the Sun. Moonlight, or the reflected light of the Sun increases in brightness as more of the Moon's surface is exposed to sunlight. Hense, the phases of the Moon each show an increasing brightness.

Now the reflected light from the Moon must pass through the Earth's atmosphere to get to your eyes. The earth's atmosphere scatters that light and diffuses it raising the effective ambient light level in the sky. The more diffuse light, the less stars can be seen. The less light, as in a new moon, the more stars can be seen. Light pollution or artificial light from cities and towns also diffuses through the atmosphere and has the same effect on your ability to see the stars as a bright Moon does.

On another note, star brightness is graded in magnitudes of brightness. Magnitude 1 is the brightess, magnitude 2 is less bright, magnitude 3 is lesser still, so on and so on. Your eyes can usually see stars of magnitude 4 or 5 on a dark moonless night near a city. In a lighted city, you may only be able to see stars of magnitude 3 or less. Out in the country away from city lights, you may be able to see stars of magnitude 7 or more. Throw in a bright moon and a little atmospheric pollution and you may only be able to see he brightest of stars and the brighter planets like Venus, Jupiter, and Saturn.

Hope this helps.

The moon reflects sunlight. Therefore, as the moon wanes into its dark phase, you have less light reflected from the moon. When you have less light reflected from the moon, you are better able to see the star-light. So, yes, the moon's phases do affect the number of stars you can see in the night sky. If you have a bright sky, because of the moons reflection of the sun, you will not be able to see so many stars.
Good luck and I hope that helps.

Yes, the moon's phases affect how many stars you can easily see. The brighter the moon, the fewer stars you can see, and the moon grows brighter and brighter as it progresses towards its full phase (..Full Moon..)

Moonlight causes glare which limits the number of stars you can see at night. Glare is a form of light pollution, which city lights also cause. Light pollution is a term which ususally refers to man-made lights at night.

think how is the moon lighted and what angle the earth is at during each phase
