The Moon has an exceptionally low albedo, giving it a similar reflectance to coal. Despite this, it is the second brightest object in the sky after the Sun. This is partly due to the brightness enhancement of the opposition effect; at quarter phase, the Moon is only one-tenth as bright, rather than half as bright, as at full Moon.
Additionally, colour constancy in the visual system recalibrates the relations between the colours of an object and its surroundings, and since the surrounding sky is comparatively dark, the sunlit Moon is perceived as a bright object. The edges of the full Moon seem as bright as the centre, with no limb darkening, due to the reflective properties of lunar soil, which reflects more light back towards the Sun than in other directions. The Moon does appear larger when close to the horizon, but this is a purely psychological effect, known as the Moon illusion, first described in the 7th century BC. The full Moon subtends an arc of about 0.52° (on average) in the sky, roughly the same apparent size as the Sun (see eclipses). The monthly changes of angle between the direction of illumination by the Sun and viewing from Earth, and the phases of the Moon that result
The highest altitude of the Moon in the sky varies: while it has nearly the same limit as the Sun, it alters with the lunar phase and with the season of the year, with the full Moon highest during winter. The 18.6-year nodes cycle also has an influence: when the ascending node of the lunar orbit is in the vernal equinox, the lunar declination can go as far as 28° each month. This means the Moon can go overhead at latitudes up to 28° from the equator, instead of only 18°. The orientation of the Moon's crescent also depends on the latitude of the observation site: close to the equator, an observer can see a smile-shaped crescent Moon.
The distance between the Moon and the Earth varies from around 356,400 km to 406,700 km at the extreme perigees (closest) and apogees (farthest). On 19 March 2011, it was closer to the Earth while at full phase than it has been since 1993. Reported as a "super moon", this closest point coincides within an hour of a full moon, and it thus appeared 30 percent brighter, and 14 percent larger than when at its greatest distance.
There has been historical controversy over whether features on the Moon's surface change over time. Today, many of these claims are thought to be illusory, resulting from observation under different lighting conditions, poor astronomical seeing, or inadequate drawings. However, outgassing does occasionally occur, and could be responsible for a minor percentage of the reported lunar transient phenomena. Recently, it has been suggested that a roughly 3 km diameter region of the lunar surface was modified by a gas release event about a million years ago.[93][94] The Moon's appearance, like that of the Sun, can be affected by Earth's atmosphere: common effects are a 22° halo ring formed when the Moon's light is refracted through the ice crystals of high cirrostratus cloud, and smaller coronal rings when the Moon is seen through thin clouds.
What else can I help you with?
Why does the moon look a little bit different every night?
The Moon appears different every night due to its changing position in relation to the Sun and Earth. This causes different portions of the Moon to be illuminated by sunlight, creating its phases. The Moon's orbit around the Earth also affects how much of its illuminated side is visible to us.
Whereabouts in the night sky can one find the Little Dipper?
The location of the Little Dipper changes from night to night (although circling around every once in a long while). In order to find it, one needs to look for Polaris, or the "North Star". Polaris is part of the Little Dipper. If you know where the Big Dipper is, you can find the Little Dipper near it.
Why do craters look different from each other?
because of the earths axis
What word begin with squ means to look in different directions with each eye?

Where is the little dipper compared with Orion?
The Little Dipper is located near Orion in the night sky. If you can find Orion, you can look to the north and slightly east to spot the Little Dipper. Orion is a prominent constellation in the winter sky, while the Little Dipper is part of the Ursa Minor constellation and is not as bright or easy to see.
Why does the earth look different each night?
The earth turns each night. Some times theirs cloud in the sky which may make it look different cause sometimes theirs not.
Why does moon look different on different night?
You are probably looking at the moon with a different perspective each night, but the face of the moon doesn't change; Only the lighting of the moon changes.
Where can I find a night stand that's a little out of the ordinary?
If your or looking for an out of the ordinary night stand, why not search antique shops for a vintage look night stand? You can also decoupage your old night stand to give it a unique and different look.
Why does the moon look a little bit different every night?
The Moon appears different every night due to its changing position in relation to the Sun and Earth. This causes different portions of the Moon to be illuminated by sunlight, creating its phases. The Moon's orbit around the Earth also affects how much of its illuminated side is visible to us.
How owl's hunt?
They hunt at night by using there vision to look for little creatures.
Is it possible to see the little dipper and the big dipper at the same time from the same location?
Yes. They are close to each other in the night sky. So if you know where to look you can see both of them.
What formal dress could be worn at night or during the day?
A little black dress can be worn day or night. You can always dress it down during the day and look casual, or dress it up at night for a more formal look.
Why is First Night called First Night when it happens on the last night of the year?
Because First night is for those who try to be different in attempt look like idiots
How would earth look different if the crust didn't move?
It would look a little different because there will be no living particle on earth
Do cheetahs have special marking?
Yep, the spots are slightly different on each cheetah. I think they look as different to each other as we do to each other.
What was thee symbal of the Nazis and what did they look like?
It looked like an X with another little stick on each end pointing in a different direction as all the others!! I hate the Nazis
Why does the moon look different every night.?
because of the rotation of the earth and the moons orbit
