Removing the moon instantly would thus change the orbital velocity by about 0.041 percent -- as a vector quantity it could be faster or slower as well as in a different direction. Between four and seven times a year, Earth, Moon and Sun line up just right to create the cosmic-scale shadow show known as an eclipse. In the case of a New Moon, the Moon is between Earth and the Sun, so the side of the Moon facing the Sun isnt facing us.

As the Moon begins its journey back toward the Sun, the opposite side of the Moon now reflects the Moons light. This diagram depicts conditions observed by NASA's Cassini spacecraft during a flyby in Dec. 2013, when Saturn's magnetosphere was highly compressed, exposing Titan to the full force of the solar w Jean Dominique Cassini (1625-1712) discovered Saturn's moons Iapetus, Rhea, But even before they could truly understand what causes the moon's phases, people learned how to use the phases as a calendar. Eventually, the length of the day will match the orbital period of the Moon. The Harvest Moon will also appear on 15 Tishrei 5763, ren-wu ji-you ren-chen, and 14 Rajab 1423. Many peoples called it the Harvest Moon because it signaled the time to gather crops and store them for the winter. The Moon takes about 27 days to make a full orbit around Earth.

Each month of a Chinese year begins at new moon and has 29 or 30 days. As the water moves, there is slight friction between the moving water and the spinning Earth. Other historical documentation, in particular accounts of climatic and societal impacts in the years 11091111 CE, corroborate the hypothesis that an 1108 eruption (or a series of eruptions that began that year), could have led to disastrous effects on affected communities.
