The moon is by far the biggest and most easily recognizable object in earth’s atmosphere that can be perceived by the naked eye on a cloudless night. It is hypothesized that it came into existence nearly 4.5 billion years ago, from residual debris after a planetary body collided with earth. Although, considered the runner-up to the sun as the second brightest object in the sky, its illumination is deceitful, insomuch as the moon is not a source of light, but instead reflects the sun’s illumination from the half of the moon that is in direct alignment with the sun at that time.

The moon is by far the biggest and most easily recognizable object in earth’s atmosphere that can be perceived by the naked eye on a cloudless night. It is hypothesized that it came into existence nearly 4.5 billion years ago, from residual debris after a planetary body collided with earth. Although, considered the runner-up to the sun as the second brightest object in the sky, its illumination is deceitful, insomuch as the moon is not a source of light, but instead reflects the sun’s illumination from the half of the moon that is in direct alignment with the sun at that time. More readily identified as a satellite of the earth rather than as a planet itself or even a star, it has a diameter a quarter of the size of earth’s size and it lacks an atmosphere, although date suggests a possibility that water may exist in the form of ice some embedded in craters near it’s North and South Pole. Similar to earth the moon posses a crust, mantle and core and is composed of comparable minerals such as oxygen, silicone, magnesium, aluminum, etc… The Moon orbits the Earth in roughly 27.3 days, however its lunar phase cycle which spans from new Moon to new Moon is approximately 29.5 days. The eight divergent phases of the moon that occur during the span of a month and are exhibited as it travels along its orbit around earth. The moon phases as the occur are New, Waxing Crescent, First Quarter, Waxing Gibbous, Full, Waning Gibbous, Third Quarter, and Waning Crescent Moon. The new moon
