<P> A lunar eclipse occurs when the Moon passes directly behind Earth and into its shadow . This can occur only when the Sun , Earth , and Moon are exactly or very closely aligned ( in syzygy ) , with Earth between the other two . A lunar eclipse can occur only on the night of a full moon . The type and length of a lunar eclipse depend on the Moon 's proximity to either node of its orbit . </P>
