Orbits of Earth and Moon. Looking at a two-dimensional diagram, you might wonder why there isn't an eclipse every month. The answer is that the Moon's orbit is slightly tilted with respect to the Earth's orbit.  The two points where its orbit crosses Earth orbit are called nodes.  Only if the Moon is full when it's near a node do the Sun, Earth and Moon line up for a lunar eclipse. ©Mona Evans, “Lunar Eclipses” http://www.bellaonline.com/articles/art28454.asp
