how come when in alaska u see the sun and moon in the sky and the moon still has a shadow of earth?

Question

I dont understand why the moon wouldnt look full all the time since theres aviosly a straight line between the two is are perception flaud why is there a shadow from earth when u can clearly see both objects in the sky

Answer 1

Yes, as has been explained by others here, the shadow you see on the Moon is not caused by the Earth, but by where the Sun is and its angle of light on the Moon.

You are under the mistaken impression that the Moon, Earth and Sun are in a perpetual, never-ending Lunar Eclipse. Lunar eclipses take place only about 2 or 3 times a year, and Solar eclipses about twice a year.

Eclipses only happen during those times when all 3 bodies line up in a straight line as seen from outer space. Normally, they are not in a straight line. That's why we see different shadows of the Moon, cast by the light of the Sun, from our vantage point on Earth.

Answer 2

Well, Alaska is a magical place...
Actually the Earth doesn't block the Sun's light from reaching the Moon, the Moon appears less than "full" due to it's spatial relationship to the Sun from the perspective we see on Earth. If the we view the Moon from an angle we see the "unlit" side (dark crescent). The Moon appears full when we view it relatively straight on in terms of it's position to the Sun. You can get the same effect with a flashlight and a baseball in a darkened room. Shine the light on the ball and move it closer to the light and then farther away. When the ball is far away from the light it will appear "full" to you. When it's is closer to the light you will see the back side of the ball and you'll note the classic crescent shape the shadow of the light creates.
But again, Alaska is a magical place :-)

Answer 3

The phases of the moon are not caused by the shadow of the Earth. Shadowing of the Moon by the Earth is a lunary eclipse.

At all other times, a partial Moon is caused by the fact that the Sun is not fully illuminating the face of the Moon that we can see from the Earth, so the partial Moon is actually the Moon's own shadow. Waning Moons are visible during day, waxing Moons are visible during the night

Answer 4

Half of the moon is always lit, but you don't always see the lit half from earth.

As the moon moves in its orbit, sometimes it is between the Sun and Earth; when that happens, all we can see here is the unlit half of the moon.
