Definition Eclipse Lunar

Eclipse Lunar usually occur when some or all of the sections covered by the shadow of Earth's moon. This occurs when the earth is between the sun and moon on the same straight line, so that sunlight can not reach the moon because it blocked by earth.

Eclipse Lunar when the moon appeared and the sun was in opposition. every month with no opposition sun will result in the occurrence of eclipse lunar, because the slope of the field of the moon's orbit to the ecliptic plane. The intersection area of ​​the moon's orbit to the ecliptic plane will bring up a node or 2 pieces of cut points, ie the point when the moon cuts the ecliptic plane. Moon takes 29.53 days to move from one point of opposition to the other opposition point. So, should in case the eclipse lunar, will be followed by a solar eclipse because the two nodes are located on the line connecting the sun with the earth.
