There are at least two reasons.
First, the moon's orbit around the earth is not perfectly circular but slightly elliptical, so it actually varies in distance from closest (perigee) to farthest (apogee) during its month-long cycle. The effect is subtle but perceptible.
Second, there are well-known subjective factors relating to human perception that alter its apparent size, even when the actual size is the same. For example, when the moon is near the horizon it always seems larger than when it is high in the sky, because we see it in relation to distant objects on the horizon. As it rises it seems more isolated and smaller in relation to the vastness of the sky.
Of course, these are essentially just theories and the true answer has yet to be found. ____________ You may be asking about the phases of the moon. During the course of the lunar month, we are watching one lunar day as it unfolds on the surface of the moon that we can observe. During the full moon it is lunar noontime at the center of the moon's face; at new moon it is lunar midnight at the same location. This lunar day (which is the same length as our lunar month) unfolds all over the moon, but again we only observe one face of the moon from our vantage point on earth.

What month is it when its a full moon?
There is a full moon every month of the year - on rare occasion, two full moons in the same month.
How often does a full moon happen on the same date of the year?
A full moon occurs approximately every 29.5 days, which means it rarely falls on the same date each year. However, it can happen that a full moon occurs on the same date in consecutive years, but this is uncommon due to the lunar cycle's variance. In practice, a full moon on the same date can happen roughly every 19 years, following the Metonic cycle, where the lunar phases align with the solar calendar.
Is there a full moon every 28 days?
No. There is a full moon every 29.53 days. This is the synodic period of the moon, based on the length of time it takes to go from on phase to the next repetition of the same phase.
What time does the full moon rise Can it be seen in the eastern or northern sky?
The Full Moon rises at roughly the same time as the sun sets.Like every other astronomical body, the moon ... at whatever phase ...rises from the eastern horizon.
What is it called when there are 2 full moons in the same month?
The second full moon in a month is called a "blue moon."
What month is it when its a full moon?

If there is a full moon in the us is there a full moon in japan?
Yes. Everybody looking at the moon at the same time sees the same shape. When you think about it ... you can take the calendar or the newspaper and look up the date of the full moon. It gives the date, but it doesn't say anything about the location. Every location has the full moon on the same date.

yes
Why do you see a full moon?
A full moon happens when the earth is between the sun and the moon, around the time in the month when the three bodies come as close to a straight line as they can get. The plane that contains the earth's orbit is not the same plane that contains the moon's orbit. So the sun, earth and moon cannot form a straight line every month during the full moon. If there were a straight line formed every month, then there would be an eclipse of the moon during every full moon. When a full moon happens at one of the two 'nodes', where the moon's orbit passes through the earth's orbital plane, there will also be an eclipse of the moon that month. So, strange as it may seem, there are slight variations on the actual 'fullness' of full moons from month to month.
What is it called when there are 2 full moons in the same month?
The second full moon in a month is called a "blue moon."
Why aren't hurricanes tracks the same?
Everything is different is like asking why isnt every hill the same.
Why is every moon not the same?
every moon looks like ice cream
What are 2 full moons in a month called?
Two full moons in a single month are called a "blue moon." The term typically refers to the second full moon that occurs within the same calendar month, while the first full moon is simply referred to as the regular full moon. This phenomenon is relatively rare, happening approximately once every two to three years.
