The orbit of the Moon is not in the same plane as the plane of Earth's orbit around the Sun. So the Moon is only seldom lined up directly behind the Earth from the Sun. However, because of the larger size of the Earth, lunar eclipses are more frequent than solar eclipses, occurring at least twice a year (either total or partial).

Why isnt every full moon the same?

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.

Why isnt there a solar eclipse and a lunar eclipse each month?

because it takes a while for the moon to come right im between the sun and earth in the solar eclipse.


Isnt true that eclipse can effect your life?

Eclipses themselves will not have any effect on your life. An eclipse is no different from night. Philosophically, the emotions that you feel while viewing an eclipse can be quite powerful. And if you are staring at the eclipsed Sun during a solar eclipse, the moment at which the Moon moves to reveal the Sun, the sunlight can seriously damage your eyes, but that's true of any time when you stare directly at the Sun.
