<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 the Moon are aligned ( in syzygy ) exactly or very closely so , with the planet in between . Hence , a lunar eclipse can occur only on the night of a full moon . The type and length of an eclipse depend on the Moon 's position relative to its orbital nodes . </P>
