8 Phases Of The Moon, .Each Lunar Month What causes the moon phases? How Total Lunar Eclipse Occurs 1.Umbra: Zone where Earth blooks all direct 2.Penumbra: Region where Earth blooks Gsome sunlight - total ealipse. (but not all) Sun ravs The moon appoars in various phases, starts by the New Moon Phase, transforms into the Waxing Crescent, appears as a Full Moon and ends in a Waning Croscont. Lunar Eclipse starts when moon gets into Earth's shadow. Sun rays Moon enters into the Earth's shadow during its rotation around the Earth. One half of the moon surface is always illuminated by the Sun rays as it faces the Sun while the other half is always dark. However, people on Earth see the illuminated half from different viewing geometries depending upon the moon's angle to that specific part of the oarth during its rotation, which causes the Moon phasos. Moon Earth Sun rays Moon moves away from the Earth's shadow marking the end of Lunar Eclipse. Difference between Lunar eclipse and moon phases Real timing Steps of a Lunar Eclipse . It takes the moon a full lunar month to show its various phases during its rotation around the Earth. On the other hand, during the phenomenon of lunar eclipse, one can observe all the shapes the moon takes during the various phases in a short span of time. Within a period of only 4 hours the moon can be viewed in a partial eclipse, total Eclipse as well as during the ending phase. (A partial lunar eclipse occurs when only a portion of the Moon 3:45 '5:32 7:18 PM PM PM Partial Lunar Eclipse starts when moon enters The deepest access of the moon into the Earth's shadow implies Total Eclipse Lunar Eclipse ends enters the umbra. When the Moon travels Earth's shadow. completely into the Earth's umbra, one can observe a total lunar eclipse). Solar system (Earth & Moon Relationship) The Bigger Moon Represents the phase of the moon as the observer on Earth views it. Moon The Smaller Moon Represents the moon's position on its orbit (showing the always illuminated half. 3 First Quarter arahs orbit ardund S Waxing Crescent The first quarter called a "half moon", happens when the moon is at a 90 degree angle with respect to the earth and sun. So we Waxing Gibbous In the solar system the eight planets orbit around the sun. The time each The moon moves planet takes to complete a cycle around the sun represents one year for that particular planet. Some planets have moons orbiting the planet itself while the planet orbits the sun. The After the first quarter, the sunlit portion starts increasing which results in the around the Earth, to position itself at a 45 degree angle with respect to the earth and sun, changing its previous alignment position. So we see a illumination of more are able to observe exactly half of the moon illuminated than half, so it is waxing gibbous. earth has one moon that rotates around it. The moon takes about one month small part of the illumi- (lunar month) to complete an orbit around the earth.

So, once the Earth completes one cycle around the sun, the moon revolves around the nated half. The new moon occurs when the moon is positioned between earth 12 times. the earth and the sun. 45 Degree angle The three objects are in approximate Sun, Moon & Earth alignment line Degree angle alignment. The entire illuminated portion of the moon is on the other half that we cannot see. 5 Full Moon Here a total lunar eclipse could only During a full moon phase, the earth, the moon, and the sun are in approximate alignment, just like the new moon, but this time the moon is occurs. on the opposite side of the earth, so the entire sunlit part of the moon is facing us. The shadowed portion is entirely hidden from our view. 6 Waning Gibbous 8 Waning Crescent After the full moon (maximum illumina- tion), the light continually decreases. So the waning gibbous phase occurs next. Following the third quarter, the moon is at a -45 degree angle with respect to the earth and the sun. In 7 Third Quarter this phase, the moon wanes until the light is completely gone so Called a "half moon" same as the First Quarter phase, It happens when the moon is at a 90 degree angle with respect to a new moon starts again. the earth and sun.
