Is a full moon is nine times brighter than a half moon?

Answer 1

Because the sun is roughly 390 times farther from us than the moon is.

As you know, if you always travel at the same speed, like light does, then the time

that any trip takes will depend directly on the length of the trip.

Answer 2

The sun does exert gravitational force on earth, but since we are in the state of free fall with respect to sun we do not feel the force, just as a falling body on earth will not feel the gravitational pull of the earth until it hits. Another way of saying this is that it is the sun's gravity that keeps the earth in orbit around the sun. We are all orbiting around the sun along with our planet.

Answer 3

The sun is bigger then the moon because stars are much much bigger than planets which includes the moon. As a matter of fact even though we see the stars in the sky as small cirular balls they are as a matter of fact much much bigger than the earth itself.

Answer 4

The sun's apparent magnitude is -26.74, while the mean apparent magnitude

of the full moon is -12.74, so their magnitudes differ by a convenient 14 .

6 magnitudes = a factor of 100 in brightness

14 magnitudes = [ 100(1/6) ]14 = 100(14/6) = 46,416 times as bright

Answer 5

Bright sunlight provides around 100,000 lux, while moonlight (full moon) is only around 0.2 lux. There is a huge difference, but our eyes are able to adjust very well to light levels so we don't notice the difference as much. Sunlight is around 500,000 times brighter than full moon light.

Answer 6

That's about right. When full, the Sun's light is reflected more directly AT the Earth, while at the quarters, much of the light that hits the Moon is reflected away - and only a small portion is scattered toward the Earth.

Answer 7

You forget two things:

1. The moon IS already orbiting around the sun

2. The closer you get to an object, the stronger it pulls

We humans on Earth do not go flying off to be with the sun because we are close enough to the Earth for it to hold us to its surface, the moon is similar.

Another point is that the moon is already orbiting around the sun with the Earth. Even if there was no Earth, the moon would stay in relatively the same position.

Answer 8

Which came first, the chicken or the egg? Where does a circle begin?

Neither came first; it's a cycle. The Moon goes through all of its phases and then does it again. To say "which came first", you'll need to arbitrarily define a starting point.

Answer 9

Sunlight (as the name suggests) come directly from the sun while the moon reflects sunlight and does not emit any light. Therefore moonlight has only 7% the intensity of sunlight and that is only during a full moon.

Answer 10

The Earth is constantly falling toward the sun. But it has enough speed 'sideways' so

that by the time it falls a mile closer to the sun, the sun's curved shape curves a mile

farther away. So the Earth never gets any closer to the sun. This kind of a set-up is

called an "orbit".

And by the way . . . The Earth pulls on the sun with exactly the same gravitational force

as the sun pulls on the Earth. Gravity always works both ways. The Earth weighs the same

weight on you as you weigh on the Earth.
