The Moon

The moon is the only natural satellite on Earth. Orbital: 384,400 km from the earth: 3476 km Weight: 35e 22 kg is called Luna by Romans, Selene by Greeks, and Artemis, and has many other myths also. Of course, the moon has been known since prehistoric times. It is the second brightest object in the sky after the sun. As the moon circles the earth once a month, the angle between the earth, the moon, and the sun changes; I think this is the cycle of the moon's phases.

Between the new moon and the full moon, the moon is a new moon (less than half is illuminated). Then the wax will grow - it will be a half moon (half illumination). At that time, the moon is one quarter of the cycle of the month, so the first half of the month following the new moon is called the first quarter. After the first quarter, there was a rising month (more than half was illuminated), lastly there was a full moon. The main stages of the month - the new moon, the first quarter, the full moon, the last quarter and the next new moon - have an average interval of 7.4 days. If you need help in tracking these phases yourself (or if you want to see the moon on an important historical day), NASA will have a date and time on the phases of the moon of 6,000 years from 2000 to 4000 Provide online calendar.

The full moon is the phases of the moon when the moon moon illuminates the earth. This phase occurs when the earth is between the moon and the sun. About a week later, the moon entered the quarter of the lunar month. At this point, only half of the surface of the moon can be seen from the earth, so the moon looks like a semicircle. When the moon moves between the earth and the sun, the side facing the earth is completely dark. This is called the New Moon Phase, and we usually do not see the moon at this point. Sometimes, you can almost understand the outline of the new moon in the sky. This is because sunlight reflects off the Earth and hits the moon. Before and after the quarter moon phase are uplift and new moon phase. During the expanse of the moon, the moon was illuminated more than half, but it was not full. At the new moon stage, the moon is considered less than half as bright and has only one sliver or crescent shape.
