The moon can be seen somewhere in the sky, at some time,
on 27 or 28 days out of every 30 .
They appear to be the same size, as the sun is a very long distance away. The sun is many times larger than the moon.
The moon appears larger at times due to an optical illusion called the "moon illusion." This occurs when the moon is closer to the horizon, making it appear larger compared to when it is higher in the sky.
Roughly four (4) times as large.
In terms of diameter, the Sun is 400 times the Moon's diameter. It is also 400 times as far away and this means that the disk of the moon and the sun appear the same size when viewed from earth.
A new moon may appear once or twice each month.
A full moon appears 12 times a year or once a month.
The term "blue moon" refers to the second full moon in a calendar month, which happens roughly every 2.7 years. The moon does not actually appear blue in color. The phrase "once in a blue moon" has led to the misconception that the moon can appear blue at times.
In the King James version the word - moon - appears 51 times the word - moons - appears 11 times
Yes because of the motion around the sun

Earth has about 50 times the volume of the Moon (and 81 times the mass of the Moon).
Because the sun is thousands of times as far away and just as many times bigger. This is simple geometry. As to why they have this relationship so that they appear to have the same diameter - it is just chance.
