Because the moon's orbit is slightly inclined from the plane of the ecliptic. The ecliptic is the path that the sun appears to follow in the sky, caused by the path of the earth's orbit around the sun. The moon's orbit is inclined about 5 degrees from the plane of the earth's orbit around the sun. The moon crosses the ecliptic about twice per month. If this happens during a new moon, a solar eclipse occurs, during a full moon, a lunar eclipse occurs. http://csep10.phys.utk.edu/astr161/lect/time/moonorbit.html http://en.wikipedia.org/wiki/Ecliptic http://en.wikipedia.org/wiki/Moon

every 6 months For a lunar eclipse. solar eclipse take a lot longer.
no. the moon is going through one of its phases, but a lunar eclipse will not always happen during this as a lunar eclipse can happen in any phase.
Mercurey and Venus do not have a lunar and solar eclipse because they do not have any moons.

every 420 years
They do happen in every state of the USA, you just have to wait for them. Lunar eclipses can be seen from half the Earth (the dark half), so you see more lunar eclipses than solar ones, which are just as frequent but can only be seen from a relatively small area of the Earth's surface.
The lunar eclipse can only happen when the moon is full.
