New Moon Sighting Phase

The Moon is the only natural satellite of the Earth, and is the largest natural satellite in the Solar System-5. Moon does not have its own light source and the light of the Moon actually comes from the reflection of sunlight. We will study how the New Moon Sighting Phase.

The average distance from the Earth-Moon center to center is 384 403 km, about 30 times the diameter of Earth. The diameter of the Moon is 3,474 km, slightly smaller than a quarter the diameter of Earth. This means that the volume of the Moon is only about 2 percent of the volume of the Earth and the pull of gravity at its surface about 17 percent than the gravitational pull of the Earth. The Moon orbit around the Earth once every 27.3 days (the orbital period), and the periodic variations in the Earth-Moon-Sun responsible for the phases of the Moon are repeated every 29.5 days (the period sinodic).

New moon sighting phase shape that is always changing when viewed from Earth. The lunar phase depends on the position of the sun seen from the moon to the earth. Phases of the moon sighting is also called aspect months.

New Moon Sighting Phase

Here is a description of each of the phases of the Moon:


New Moon Sighting Phase

Phase 1 - New Moon (New Moon): The side of the earth facing the moon does not receive light from the sun, the moon is not visible.

Phase 2 - Waxing Crescent (Crescent Junior): During this phase, less than half of the moon that lights up and as the phase progresses, gradually illuminated portion will be greater.

Phase 3 - Third Quarter (Quarter III): Moon reaches this stage when half of it is visible.

Phase 4 - Waxing Gibbous: This phase is characterized Earlier when the moon is half the size. As the phase progresses, parts lists will be greater.

Phase 5 - Full Moon (Bulam full moon): The side of the earth facing the moon light from the sun actually, the entire moon is visible. This occurs when the moon is on the opposite side of the Earth.

Phase 6 - Waning Crescent: During this phase, part of the moon as seen from Earth is gradually becoming smaller.
Phase 7 - First Quarter (First Quarter): The Moon reaches this stage when half of it is visible.

Phase 8 - Waning Crescent (Crescent older): Only a small portion of the moon visible in the phase which gradually becomes smaller. The simple explanation phases of new moon sighting feels it would be easier to put across the lunar cycle to know the New Moon phase / New and Full Moon, First Quarter and Third Quarter and the phases in between.

Death or New Moon sighting occurs during approximately the Moon are in a straight line between the Sun and the Earth (Why more or less will be explained below). The entire surface of the moon is illuminated by the sun is in the "back" months, in part we can see from Earth.

At Full Moon, the Earth, the Moon and the Sun back more or less are in one straight line, tetapipada opposite position, such that the entire surface of the sunlit months dealing with us. Dark side hidden "behind".

First quarter and the third quarter of the moon phase (both often called Half Moon (Half Moon) occurs when the position of the Moon, Earth and Sun form a 900 angle so we see exactly half of the moon is lit by the sun and the dark half again.

By knowing the fourth phase above the other four phases will be easier to understand, because it is a picture of the process of transition from one phase to the next phase

To make it easier to remember and understand the four other phases that we term; Crescent (Crescent), Gibbous, Waxing (enlarged) and Waning (shrinking).

Sickle (crescent) shows the phase in which the moon was impressed irradiated less than half of its surface. While Crescent moon illuminated indicates the phase in which more than half of its surface. Waxing in principle show enlargement or expansion of irradiation. While Waxing is a diminution or deduction of irradiation. A few explanations about New Moon Sighting Phase.
