Lunar Eclipses MCQs and Answers: What is Lunar Eclipses?
A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the Sun, Earth, and Moon are aligned (in syzygy) exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur on the night of a full moon. The type and length of an eclipse depend upon the Moon’s location relative to its orbital nodes.
Lunar eclipses happen up to three times per year, although some years may pass without any eclipses at all. There are two types of lunar eclipses: total and partial. Total lunar eclipses happen when the entire surface of the Moon passes through Earth’s umbra; partial lunar eclipses happen when only a portion of it does so. A typical total lunar eclipse lasts for about an hour and forty-five minutes.
