a total lunar eclipse
A new moon phase is happening when the moon is aligned between the Earth and the Sun. During this phase, the side of the moon that is illuminated by the Sun is facing away from Earth, making the moon appear dark or invisible from our perspective.
An eclipse happens when the Sun, the Moon and the Earth line up almost exactly. When the shadow of the Moon falls on the Earth, this is a solar eclipse. When the shadow of the Earth falls on the Moon, this is a lunar eclipse. On average, there are two solar eclipses and two lunar eclipses each year. About half of these are partial eclipses, in which the Sun, Moon and Earth don't QUITE line up exactly.
It is a solar eclipse. The Moon passes across the face of the Sun, and blocks out the sunlight for a short period, so casting a shadow on the Earth.
Only Earth has exactly one moon.
The moon orbits the earth at an average distance of 226,000 miles, while the earth orbits the sun at a distance of around 93,000,000 miles.

The "new moon" is when the Moon passes (almost) between the Sun and the Earth. The next new moon will be on November 16, 2009.If the Moon were to pass EXACTLY between the Sun and the Earth, there would be a solar eclipse.
At the full moon, the Moon and the Sun are on approximately opposite sides of the world, with the Earth roughly in between them. If the Earth were EXACTLY in between them, we would have a total lunar eclipse. But at the full moon, the Moon is normally a couple of degrees above or below the line from the Sun to the Earth. Partial and penumbral lunar eclipses happen when the Earth is NOT QUITE exactly in between the Sun and the Moon.
That's Full Moon. If the arrangement is in exactly the same line, then there's a lunar eclipse.
Obviously there's a mistake in this question. I suppose "the Earth" should be in there somewhere.
The "New" moon is single point in time, when the moon is between the Earth and the Sun; it doesn't last even one hour. If the Moon is exactly between the Sun and Earth, then the shadow of the Moon will hit the Earth; we call this an "eclipse of the Sun".
In a gravitational situation, the forces are exactly equal in both directions.-- The Earth attracts the moon with a force that is exactly the same as the forcewith which the moon attracts the Earth.-- You attract the Earth with exactly the same amount of force as the Earth attracts you.-- Your weight on Earth is exactly the same as the Earth's weight on you.
That's Full Moon. If the arrangement is in exactly the same line, then there's a lunar eclipse.
Yes, every month. When the Moon is almost between the Earth and the Sun, the Moon is "invisible" or "new", meaning that you can hardly see it because of the Sun's glare. (When the Moon is EXACTLY between the Earth and the Sun, we get a solar eclipse.) In 29.5 days, it will be right back there again.
The moon and earth are always exactly in line; any two points define a line. When the earth moon and sun are all exactly in line, that is different. When this happens it is either a solar eclipse or it is a lunar eclipse.
On the average, 365.24 days ... exactly the same as the earth's orbital period. If it were not exactly the same as the earth's orbital period, then the moon would either lead or lag the earth in the trip around the sun. It would certainly become noticeable ... if not immediately, then certainly over the course of a few hundred years. But that's not happening.
