If Earth had no atmosphere the answer would always be exactly 50% at all times. That's the exact percentage of the moon's surface and the surface of Mercury that's illuminated by the sun at all times. The actual answer for Earth is slightly more than 50% because the atmosphere bends sunlight downward when the sun is on the horizon. In fact, at sunrise and sunset you can see the sun when it is actually a little below the horizon. I don't know the exact percentage, but here are some facts to give you a good idea: Along the equator the time from sunrise to sunset is the same every day of every year, and that time is 12 hours and about 7 minutes. Also, in September, the sun rises at the south pole more than four days before the sun sets at the north pole.
What else can I help you with?
How much of the Moon's surface is illuminated by the sun at any time regardless of how much of that light can be seen from earth?
At any given time, one half of the Moon's surface is illuminated by the sun, just like on Earth. The portion of the Moon's illuminated side that we can see from Earth depends on its position in its orbit around our planet.
Is 100 percent of the moon being illuminated during the full moon?
No. Only half of the moon is illuminated at any one time. During a full moon, the half facing Earth is fully illuminated.
When is virtually the whole Earth illuminated in a 24-hour day?
Never.Half of the Earth is illuminated by the sun,and the other half is getting no direct sun.This statement holds for any moment in time, 24 / 7 / 3651/4 .
What does full moon phase mean?
The time in which the whole face of the moon is illuminated - when the moon is on the opposite side of the Earth as the sun.
One side of the earth is facing the sun and the other side is what?
The side facing the sun experiences daytime, while the side facing away experiences nighttime. This is due to the earth's rotation on its axis, which causes different parts of the planet to be illuminated by the sun at different times.
What is the approximate percentage of the Earth that is illuminated by thesun at any given time?
Exactly one half, 50%,
How much of the Moon's surface is illuminated by the sun at any time regardless of how much of that light can be seen from earth?
At any given time, one half of the Moon's surface is illuminated by the sun, just like on Earth. The portion of the Moon's illuminated side that we can see from Earth depends on its position in its orbit around our planet.
What portion of earth receives energy form the sun at any given time?
Since the Earth is a Spheroid shape, (not a true sphere) 50% of its surface is illuminated by the Sun, at any given moment.
Why does it look like the moon is changing?
Because the sun, the moon, and the Earth are constantly changing their relative positions with respect to each other, different parts of the moon are illuminated by the sun, from the viewpoint of a given observer at a given time. The part of the moon that is not illuminated can't be seen from Earth, it is just a dark moon against the darkness of space.
Is 100 percent of the moon being illuminated during the full moon?
No. Only half of the moon is illuminated at any one time. During a full moon, the half facing Earth is fully illuminated.
What portion of the moon is always illuminated?
Half of the Moon, just like Earth and the other planets, is more or less illuminated all the time. The half that is illuminated is the half that faces the Sun. The illuminated half continually changes as the Moon orbits and revolves. The exception is when the Earth gets between the Moon and the Sun, shading the Moon. (an eclipse).
In whaty phase can the moon not seen from the Earth?
New Moon. At that time, the entire illuminated side of the moon faces away from earth. When welook at the moon, we're looking at the entirely un-illuminated side, and we see nothing.
When is virtually the whole Earth illuminated in a 24-hour day?
Never.Half of the Earth is illuminated by the sun,and the other half is getting no direct sun.This statement holds for any moment in time, 24 / 7 / 3651/4 .
Explain the moon sometimes appears as a crescent?
At that time, there is still exactly half of the moon illuminated by the sun. But from our position on earth, we can only see a small part of the illuminated half.
What fraction of the earth surface is illuminated by the sun?
All of it though not at the same time. At any point in time, it is a little over a half.
Why you see 50 percent of the moon?
Over time you can see about 56% of the lunar surface from the Earth, this is because the (almost) spherical Moon "wobbles" while orbiting the Earth and so we eventually can see a little more than the half that is facing us at any given time.
What percentage of the Moon is lit?
The moon is ALWAYS 50% (+/-) illuminated. Though we only see all of the half lit side when the moon is opposite the sun (Full Moon).
