Why this color?
From: "j james"
why is the moon white?
brad answered with these two ideas:
the moon is white for two reasons. 1.
Because the moon is made up a bunch of dust and stone particles. 2.
because the sun reflects off the moon without the sun we wouldn't be
able to see the moon.
TB helped out with this:
The Moon appears white most of the time
because it reflects the sunlight falling on it. In the morning and
evening the Moon may appear red due to the bending of the reflected
light in the Earth's atmosphere.
amrshalakanidr believes this:
The moon isn't white at
all...it has a grayish sand & rock covered surface.....but due to
the reflection of sun's light upon it back to earth and through our
atmosphere... it does appear as being white......sometimes it even
appears red when the sky is dusty of some sort...
Stu rattled off this answer:
The Moon isn't really white. Actual fact,
it is a variety of tones of grey. If you are wondering why the Moon
looks so white when it is full and overhead (not on the horizon),
this is because the surface of the Moon is covered with silica dust.
Silica dust has some glass-like properties. It reflects light
brightly when the the light
source is coming from a perpendicular or near perpendicular angle.
Hence when it
is a full moon the Sun light is is hitting the Moon more directly
and since the Earth is sharing that near perpendicular angle we see
the brightest reflection of the Sun's light off of the Moon's
Todd replied with this:
Well the moon really isn't white. It
looks white at night time because you are seeing white light
reflecting off the moon. If you look closely you can see some spots
of grey. The moon is actually grey and it only appears to be white
because of the light it reflects.
Jelly Bean added this:
The moon is white when its
position in relation to the earth allows it to reflect more
sunlight. When you see a yellow or orange moon, its because less
sunlight is being reflected, and you see more earth light. Thats
what happens in a lunar eclipse--the earth is right between moon and
sun, and ALL you see is earth light- red.
conchita estela(Kimmi Lauren's sister) responded
not actually white...just appears to be...it glows because of the
suns rays when they reflect off of it...so it appears to be white.
the moon is grey...grey moon dust
Xyleman concluded with this thought:
The moon is not necessarily white; it
just has very little color. The moon is actually varying shades of
grey, depending on the relative albedo (reflectivity) of its
surface. Less reflective areas appear darker, more reflective
surfaces appear brighter. The light of the moon is reflected
sunlight, which apears white to our eyes. The moon has no
atmosphere, which gives color to some planets, nor does it have
distictive chemistry that gives rise to certain colors, such as the
ruddy hue of Mars. Basically the moon is just a grey place.
