Is a new moon and no moon are same?
Yes. A new moon appears as if there is no moon in the sky, but it is actually there.It is the same as the new moon is not visible (too close to the Sun). It is visible later when followed by the Moon's first visible crescentWhen the Sun and Moon are aligned on the same side of the Earth the Moon is "new", and the side of the Moon visible from Earth is not illuminated by the Sun.As the Moon waxes (the amount of illuminated surface as seen from Earth is increasing), the lunar phases progress from new moon, crescent moon, first-quarter moon, gibbous moon and full moon phases, before returning through the gibbous moon, last-quarter (or last quarter) moon, crescent moon and new moon phases.The terms old moon and new moon are interchangeable, although new moon is more common.
What are some characteristics of a full moon?
At a full moon, 100% of the visible surface of the Moon is illuminated by the Sun. Half of the Moon is always illuminated by the Sun, and half of the Moon is visible from Earth. But they're not usually the same half. At a full moon, they are. This happens when the Sun, Earth and Moon are approximately lined up in the sky. If the alignment is exact, we'll have a lunar eclipse because the Moon will pass through the Earth's shadow, which is the only time that less than half of the Moon is lit up.
Why can we see moon on a full moon day while it is not visible on a new moon day?
Moonlight is reflected sunlight. When the moon and sun are on opposite sides of the earth the face of the moon we can see is illuminated and it is a full moon. When the sun and moon are on the same side of the earth then the side of the moon away from us is illuminated.
Do The phases of the moon depend on how much of the lighted side of the moon can be seen from Earth?
Yes. There is always (except during certain eclipses) half of the moon illuminated. However, there is no 'dark side of the moon' per se. The same part of the moon is always facing the earth, but the part that is lighted changes by the minute, just as it does on Earth.
Is the moon always the shape of a circle?
The moon is a sphere. It is illuminated in our night sky when the sun shines on it. The sun always illuminates the same side of the moon. The moon's apparent shape - the shape we see - the part which is illuminated ranges from a left-facing thin crescent to a full circle to a right-facing thin crescent. This is because, due to the rotation of the earth, we are not always facing head-on to the side which is illuminated.
What is the minimum percent of the moon that needs to be illuminated in order for the phase to be called gibbous?
A "gibbous" Moon has between 51% and 99% of the illuminated side of the Moon visible from Earth. Just to be precise; the Moon is always 50% illuminated. The Moon is a rocky ball, half in sunlight and half in darkness. As the Moon orbits the Earth, the same face of the Moon is always visible. From the Earth, we see "phases" of the Moon as the Moon orbits the Earth. At the new moon phase, the illuminated half of the Moon is the "far side" of the Moon; at the full, the illuminated half is the "near side".
Is the moon always dark on one side?
No. The Moon is orbiting the Earth, but is illuminated by the Sun. About half of the Moon's total surface is illuminated by the Sun at any one time. As the Moon orbits the Earth, the same side always faces the Earth. The phases of the Moon represent the part of that face that is lighted on that particular day. We cannot see the far side of the Moon, but it will have the remaining part of the illuminated one-half.
If it's a crescent moon at the north pole can it be a full moon on the same night somewhere else?
No. Everybody anywhere on earth who can see the moon at all sees the same illuminated shape at the same time.
Does the earth and the moon have the same amount of mass?
No, they do not have the same mass. The moon has much less mass than Earth.
Where is moon when half lit?
The moon's phases result from the changing relative positions of the Earth, Moon, and Sun. It doesn't matter where the moon is when it's half-lit (or in its first quarter); its position relative to Earth and the Sun does matter, however. When the Sun and Moon are aligned on the same side of the Earth the Moon is "new", and the side of the Moon visible from Earth is not illuminated by the Sun. As the Moon waxes (the amount of illuminated surface as seen from Earth is increasing), the lunar phases progress from new moon, crescent moon, first-quarter moon, gibbous moon and full moon phases, before returning through the gibbous moon, third-quarter (or last quarter) moon, crescent moon and new moon phases.
Is a new moon and no moon are same?
Yes. A new moon appears as if there is no moon in the sky, but it is actually there.It is the same as the new moon is not visible (too close to the Sun). It is visible later when followed by the Moon's first visible crescentWhen the Sun and Moon are aligned on the same side of the Earth the Moon is "new", and the side of the Moon visible from Earth is not illuminated by the Sun.As the Moon waxes (the amount of illuminated surface as seen from Earth is increasing), the lunar phases progress from new moon, crescent moon, first-quarter moon, gibbous moon and full moon phases, before returning through the gibbous moon, last-quarter (or last quarter) moon, crescent moon and new moon phases.The terms old moon and new moon are interchangeable, although new moon is more common.
Does the earth and moon have the same amount of gravitational pull?
No, the earth is bigger than the moon so they don't have the same gravitational pull
What are the various phases of the Earth?
The apparent 'phases' of the earth depend entirely on where the observer is located. If the observer is standing on the moon and looking at the earth, he will see the earth go through exactly the same phases as we see the moon go through ... but they will be COMPLEMENTARY. At any moment of the month, the shape of the ILLUMINATED portion of the moon ... seen from earth ... is exactly the same as the DARK portion of the earth as seen from the moon. Combine the illuminated moon phase of the earth-bound observer with the illuminated earth phase of the moon-based observer, and they always add up exactly to one full illuminated disk.
Would a solid weigh the same amount on the moon as it does on earth?
no

Does the moon change from night to night?
The appearance of the moon changes from night to night because different parts of the moon are illuminated by sunlight, from the perspective of the viewer here on Earth. The moon itself is not changing, it remains the same.
What motion is responsible for the changing appearance of the moon?
Moon's orbit around Earthis not perfectly round but is oval or elliptical in shape. As the Moon orbits our planet, it's distance varies from about 221,000 to 252,000 miles. This 13% variation in the Moon's distance makes the Moon's apparent size in our sky vary by the same amount
