What causes a lunar eclipse?
Answers
Answer:
The primary condition required for a lunar eclipse to occur is that the sun, the earth, and the moon should be exactly or very closely aligned, with the earth being positioned between the other two. This blocks the light of the sun from reaching the moon’s surface, thereby casting its shadow on the moon and causing a lunar eclipse.
Explanation:
A lunar eclipse occurs when the Moon moves into the Earth's shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned with Earth between the other two, and 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. Lunar eclipses occur when Earth's shadow blocks the sun's light, which otherwise reflects off the moon. There are three types — total, partial and penumbral — with the most dramatic being a total lunar eclipse, in which Earth's shadow completely covers the moon.
