The moon and sun have the same orbital position during the new moon phase. At this time, the moon is positioned between the Earth and the sun, making it difficult to see the moon from Earth. This alignment means that both celestial bodies share the same ecliptic longitude, resulting in the moon being in conjunction with the sun.

Why is a lunar month longer than the number of days it takes the moon to orbit the earth?
The lunar month refers to the time it takes the moon to get back to the same phase (for instance, from one New Moon to the next). The moon needs to get to the same part of its orbit where the Sun is in the same position for an observer on Earth. The Moon has to take another 2.2 days to "catch up."
Why is the moon sometimes visible during the daytime?
The moon is sometimes visible during the daytime because its position in its orbit around the Earth causes it to be in the sky at the same time the sun is. Depending on its phase, angle, and position relative to the sun and Earth, the moon can be visible during the day.
Why is the Moon's orbital period different from its phase period?
Good question, its to do with the difference between the sidereal rotational period and the synodic rotational period. Relative to the background stars, the moon takes 27 days 7 hours and 43 minutes to orbit the earth - the sidereal orbit. Ignoring the sun and just looking at the earth from above the north pole, with the moon in orbit around it, this is the time for the moon to circle once around the earth. During this time though, the earth has progressed around the sun somewhat, on its orbit around the sun. For the moon to get back to exactly the right phase, it takes a little longer, 29 days, 12 hours and 44 minutes in total from full moon to the next full moon. This is known as the synodic period. This is due to the portion of the orbit, the curve that the earth has progressed it that time. The phase of the moon maybe the same again after this synodic period, but the moon will have made just over one orbit relative to the background stars, and will have moved round slightly to be in front of some different stars to those at the previous full moon.
What would happen if the moons orbit were completely in the same plane as the earths orbit around the sun?
If the Moon's orbit were in the same plane as Earth's orbit around the Sun, we would experience a solar eclipse every month during the new moon phase as the Moon would pass directly between the Sun and Earth. This alignment would likely have a significant impact on Earth's tides and possibly cause more extreme weather patterns due to the gravitational influence of the Moon.
Does the moon change shape in a full orbit?
No - the moon itself stays the same shape. The phases of the moon change as the earth and moon orbit round the sun. The phases are simply the amount of sunlight reflected in relation to the position of the earth's shadow cast on the moon

Assume that a new orbit begins at full moon What fraction or the way around its orbit is the moon during the full moon phase?
We're going to assume that the question is referring to the next Full Moon.The moon makes one complete orbit each 27.32 days, but the phases repeat witha period of 29.53 days. So the elapsed time from any phase to the next appearanceof the same phase is (29.53/27.32) = 1.081 orbits.
How long does it take the moon to revovle around earth?
It takes our moon about 27.3216 average earth days to complete an orbit of the Earth. However, due to the Earth's progress in its orbit of the sun during that time, it takes an additional 2.2 days to get to the same phase, or position with respect to the sun, as when the orbit started.
Do eclipses occur monthly?
Eclipses of Jupiter's moons occur daily. But if you mean the regular solar and lunar eclipses, no, most of the time the Moon will pass by one of the sides of the position required for the eclipse, so there is no eclipse. That is because the Earth's orbit around the Sun, and the Moon's orbit around the Earth, are not exactly in the same plane.Eclipses of Jupiter's moons occur daily.

Is there a full moon in Indiana on 4-23-09 or a crescent or half.?
Phase of the Moon on 23 April: waning crescent with 3% of the Moon's visible disk illuminated. New Moon on 24 April 2009 at 11:23 p.m. Eastern Daylight Time. The phase of the Moon is the same for any observer in the world at that time; it all depends on where the Moon is in its orbit.

Why does the moon show in daytime?
It is because it takes the moon about one month to orbit the earth and so it is possible for the moon to be seen in the sky the same time as the sun. click on 'related links' below to see a picture of moons orbit.
Why is the moon so high in the sky?
The moon appears high in the sky because the moon is in space. We are on earth.We are on the ground and the moon is in the sky. The moon appears to be highest in the sky in the tropical regions of the world, just like the sun - since the moon's orbit is almost perpendicular to the tropics.At higher latitudes, the moon will appear lower in the sky for the same reason as the sun is.
Is the moon always in the same spot in the sky at the same time each night?
No, the moon's position in the sky changes throughout the night due to its orbit around Earth. The moon rises and sets around 50 minutes later each day, so its position at a specific time will vary from night to night.
