Lunar Phases

Lunar phases are the different appearances of the moon over the course of a lunar month, and are caused by the moon orbiting the Earth and the sun hitting the moon at different angles. The different lunar phases have names; the major lunar phases in the lunar cycle are the New Moon, First Quarter, Full Moon and Third Quarter phases.

Asked by Wiki User

The new moon phase occurs when the moon is positioned between the Earth and the Sun. During this phase, the moon is not visible from Earth since the illuminated side is facing away from us. It appears as a dark silhouette against the bright background of the Sun.

What determines when the paschal full moon occurs?

User Avatar

Asked by Wiki User

The paschal full moon is determined by a specific ecclesiastical calculation rather than astronomical observation. It is defined as the first full moon after the vernal equinox, unless that full moon falls on a Sunday, in which case it is observed on the following Sunday. This calculation is used to determine the date of Easter in the Christian calendar.

An annular eclipse is a 'ring' of sunlight around the Black Lunar Disc.

Which moon phase does the low tide occur?

User Avatar

Asked by Wiki User

There are 2 tides a day. The phase of the moon is not responsible for high and low water, but does affect 'by how much'.

Some high waters are higher than others and at the same time the tide goes out further at low water. These are known as 'spring' tides and happen when the moon is 'full' or 'new'.

So 'springs' and 'neaps' are affected by phase. The tide will still come in and out twice every day.

What will the moon phase be tomorrow?

User Avatar

Asked by Wiki User

The four major moon phases, which are about a week apart, are

  • new moon,
  • first quarter,
  • full moon, and
  • last quarter.

As the amount of sunlight we see on the moon increases from new moon to full moon, the moon is said to be waxing. As that amount decreases from full moon to new moon, the moon is said to be waning. Also, when less than half of the visible side of the moon is lit, it is called a crescent, and when more than half is lit, it is called gibbous. Inserting into the list of moon phases the descriptions of the moon between phases gives us the following list:
  • new moon
  • waxing crescent
  • first quarter
  • waxing gibbous
  • full moon
  • waning gibbous
  • last quarter
  • waning crescent
  • (new moon)

How often does each moon phase occur?

Asked by Wiki User

It takes the moon 29.5 days to go through all phases, from full moon, back to full moon for example.

Relative to the background stars and ignoring the earth position relative to our sun, the moon takes 27 days 7 hours and 43 minutes to orbit the earth - the sidereal orbit. During this time, the earth has progressed around the sun a little, 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.

How many days are there in a new moon phase?

User Avatar

Asked by Wiki User

The actual "new moon" is a moment, a point in time; it doesn't really have a duration. But for practical purposes, there is one day on which the Moon is generally not visible at all, and this is the day of the new moon. One day later, you will be able to see a thin crescent Moon - the one that some people call "Diana's Bow" - very low in the evening sky next to the setting Sun.

Most people aren't up and out in the hour before sunrise, but if you were to look up to the east just as dawn was breaking the day BEFORE the new moon, you would be able to see the crescent moon then, as well.

What is the moon phase that occurs after a new moon and only half of the lighted side can be seen?

User Avatar

Asked by Wiki User

This is the first quarter phase. The moon looks half lit, half in shadow, but you actually can only see one quarter of the moons surface at this point (during a full moon, you would only be able to see half of the moons surface - the half that faces us).

Which moon phase follows the new moon phase?

User Avatar

Asked by Wiki User

After the New moon, the next phase is the "waxing crescent". "Waxing" in the context means "growing" or increasing. The opposite is "waning", or decreasing.

What moon phase would a neap tide occur at?

Asked by Wiki User

Neap Tide is the tide that occurs when the Sun and Moon are in 'quadrature',
or 90 degrees apart in the sky. When things are arranged that way, we see
the Moon at either First Quarter or Third Quarter.

How many days does each phase of the moon take?

User Avatar

Asked by Wiki User

The Moons Revolution around earth is about 30 days. So if you divide that by 8 (because there are 8 phases) you would get about 3.75 days in between each phase. That is New, Cresent, First Quarter, Gibbous, Full, Gibbous, Third Quarter, Cresent and then once it gets back to New Moon again, its starts over again.
