Total lunar eclipse is a kind of lunar eclipse. When the moon, the earth and the sun are completely in a straight line, the earth is in the middle, and the whole moon walks into the shadow of the earth, forming a total lunar eclipse. Seen from the earth, the whole moon is bronzed, which is commonly known as the "red moon".

Causes of total lunar eclipse

When the earth, the moon and the sun are in a straight line, the earth blocks the light that the sun shines on the moon and forms an eclipse. Because the earth, the moon and the sun are constantly moving, the sunlight blocked by the earth is from scratch, and then from scratch, and the shadow of the moon is gradually changing bit by bit, so there are several forms of solar eclipse.

When the earth completely blocks the sunlight, there is no light on the moon, and a total lunar eclipse is formed. At this time, we can't see the moon clearly with the naked eye. After a period of time, when the earth leaves the sun, the moon will reappear in our field of vision bit by bit, which usually takes several hours.
