A lunar eclipse is an astronomical event that occurs when the Moon moves into the Earth's shadow, causing the moon to be darkened. Such alignment occurs during an eclipse season, approximately every six months, during the full moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit.
This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, which can happen only on the night of a full moon when the Moon is near either lunar node. The type and length of a lunar eclipse depend on the Moon's proximity to the lunar node

3. Lunar eclipse can occur only when the Sun, Earth, and Moon are exactly aligned with Earth.
4. The type and length of a lunar eclipse depend on how close the moon is to the lunar node.
