The description of the phases of the moon.
Introduction:
Moon is the one and only natural satellite of the planet earth. Other terrestrial planets also have one natural satellite. However, the Jovian planets have more than one moon that orbits the planet. The planet Jupiter has the highest number of moons, which is equal to 79 moons.
Explanation of Solution
The new moon takes place when the moon is positioned between the earth and the sun. The three objects are in approximate alignment. The complete illuminated portion of the moon is on the backside, on the half that is not visible from Earth. In the case of full moon, earth, moon, and sun are present in alignment as observed in case of the new moon, but the moon is on the opposite side of the earth, so the entire sunlit part of the moon is facing the Earth. The shadowed portion of the moon is hidden from the person watching the moon from the earth’s surface. The first quarter and third quarter moons happen when the moon is at a 90-degree angle with respect to the earth and sun. So for a person seeing the moon from Earth exactly half of the moon illuminated and half in shadow.
