Why Does The Moon Shine?

hello everyone and welcome back to our

universe today we'll be answering the

question why does the moon shine the

moon is made up of large dark volcanic

rock and no offense the moon but the

moon is not like the earth instead of a

hot core the moon is completely cold and

dead it doesn't rotate or turn like the

earth either and it faces us in the same

direction the reason that we can see the

moon glow or shine is because the light

of the Sun is reflecting off the moon's

surface and this makes it visible to us

the moon is actually made up of quite

dark material so it only reflects about

12% of the light that hits it the amount

of light that gets bounced back to earth

also depends on the time and place of

the orbit of the moon when the moon's

orbit is directly facing towards Earth

we get a large amount of light bouncing

back because there's more of the face of

the Moon facing the earth this is called

the full moon the moon appears larger

and brighter and we can usually see the

man in the moon's face really clearly as

the orbit changes the angle of light

also changes and less and less light

bounces back to earth during the various

quarter stages of the Moon it actually

only reflects 8% of the light back to

earth the moon has an elliptical orbit

so occasionally it gets closer and when

this happens and it's facing the earth

we can actually see the moon reflects

about 20% of the light and we call this

a super moon is it a bird is it a plane

no it's super moon no no that doesn't

work the light from the super moon is so

bright that astronomers cannot use their

telescopes so I'm guessing the

astronomers probably get a night off the

moon is made up of ancient volcanic rock

that is about 4.5 billion years old and

that is around about the age of the

solar system

so this is pretty old rock since there

isn't any atmosphere on the moon the

surface only changes when it's hit by

another space object for example an

asteroid and this has caused the moon to

have a lot of craters and mountains as

the angle changes of the orbit of the

moon the angle of the mountains and

craters also change and the light from

this that's reflected becomes dimmer and

when there's a sharper angle from the

light of the Sun it causes the craters

and the mountains to cast shadows this

is why we see the moon is less bright at

certain times in its orbiting cycle you

might be surprised to know that the

amount of light that we see today is a

lot less than what our ancestors saw

this is because the moon is ever so

slightly moving away from the earth the

earth and the moon both have a

gravitational pull and the moon's

gravitational pull causes the ocean

tides on the earth and thousands of

years ago the moon was much closer to

the earth and this means the people in

the distant past must have seen the moon

larger and brighter in the night sky

this is because of the amount of light

reflected was a lot more than it is


so I hope that's given you a great

insight into why the moon shines and

also what it's made of and why the moon

actually becomes brighter and dimmer at

certain points in its orbit and as
