At the new Moon phase, the Moon is so close to the Sun in the sky that none of the side facing Earth is illuminated position 1 in illustration. The answer has to do with the Earth and moon relationship to the sun. In this issue, we'll take a look at the Moon in our sky--its phases and some ways in which students can enjoy and learn from its ever-changing appearance.
The earth does cast a shadow as does any object in sunlight , but the moon usually passes above or below it.
The note and another moon watch were kept in a display case at the Hayden Planetarium for several years. Figure 1 shows the Moon during one orbit around the Earth from a vantage point far above Earth's North Pole.

The Moon takes 27. The moon appears larger than normal due to an optical illusion of perspective. On that day it rises as the Sun is setting and sets and the Sun is rising.
Polish up that telescope! These changes in phases, and the changes in when you can see the moon in the sky are caused by the fact that the moon orbits around the Earth: A portion of Mare Imbrium — another lava feature — is visible at the right bottom.
Even though about 95 percent of the moon is illuminated at this time, and to most casual observers it might still look like a "full" moon, its brightness is roughly 0. Naval Observatory.
Many people have heard that the same side of the moon always faces the earth, and because of this, many think that the moon does not rotate.
She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named 3505 Byrd in her honor. During the second half of the lunar month, the Moon grows thinner each night. More science.
