LUNAR eclipses are caused by the Earth's shadow on the Moon, so the Earth must be between the Sun and the Moon, which means a FULL Moon.
SOLAR eclipses require a NEW Moon, that is, a Moon between the Sun and the Earth.
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.
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.
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.
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.
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.
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
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.
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.
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.
the full moon is more closer to the sun than the half moon
it isn't the sun is 450000 times brighter than the moon! no..
It depends on the phases of the moon, e.g., a full moon will appear much brighter than a last quarter or first quarter moon.
Apart from the night being a bit brighter - not at all.
The shadow of the earth never falls on the moon when the moon is half full.

On the side of the moon that the sun is shining on, the temperature reaches 260°Fahrenheit! That is hotter than boiling. On the dark side of the moon, it gets very cold, -280° Fahrenheit. The moon is about 2,000 miles across.
No. The new moon is completely dark.
From our perspective, it is not brighter. It is mostly the far side of the moon that is lit up, and it is bright there, but we cannot see it.
A full cycle - e.g., from full moon to full moon - is about 29 1/2 days. From new moon to full moon is half that time.A full cycle - e.g., from full moon to full moon - is about 29 1/2 days.

The half, because the full moon is as light again.
It's the same as the sky is brighter when the Sun is up, only not as much.

The "nearside" of the Moon also receives Earthshine, sunlight reflected from the Earth which then hits the Moon. The full Earth is about 10 times brighter than the full moon!
We see more of the moon lit when it is a gibbous moon than when it is a crescent moon, so it does seem bigger. Save
