An eclipse happens because the Earth is passing between the Sun and the moon. During this passage, the Sun, moon, and the Earth are all aligned. They must be all aligned for the eclipse to occur. If only the Sun and Earth are aligned, it will result in a partial eclipse or no eclipse at all.
Some scientists result in the eclipse to the orbit around the moon, not being a full circle, which makes it not a perfect alignment. During a lunar eclipse, a full moon will also be seen. The people who are seeing the full moon may see it as the color red, which is why it has the name blood moon.
Lunar eclipses occur because the earth passes between the moon and sun. At a glance, the moon becomes darker, as it is seen from earth. The kind of eclipse depends on which part of the astronomical object is impassable. Another explanation can be that the orbit of the moon is not a perfect full circle, and it is not as perfectly aligned to the earth’s orbit around the sun.
Eclipses happen when one extortionate object gets in the way of another that the second object blocks out the glistening light emitted by the sun, and the moon passes over it, partially or fully. When earth crosses between the sun and moon, and the earth casts a shadow on the moon, a lunar eclipse occurs.
