The Earth-Moon

SystemPresentation By:Bimbo S. Marcelino

The earth-moon system is sometimes considered

a double planet.

THE MOON

The moon is the earth's nearest neighbor in space.

ECLIPSE

Eclipse are

An eclipse is an astronomical event that occurs when an astronomical object is temporarily obscured, either by passing into the shadow of another body or by having another body pass between it and the viewer.

Some people believe that the Eclipse are the sign of famine

and war.

Lunar Month

What is Lunar Month

In lunar calendars, a lunar month is the time between two identical syzygies (new moon or full moons).

A Lunar month is the amount of time it takes for the Moon to pass through each of its phases (new moon, half, full moon), and then return back to its original position. It takes 29 days, 12 hours, 44 minutes and 3 seconds for the Moon to complete one lunar month.

New Moon And Full Moon

New Moon

The new moon is the lunar phase which happens when the Moon is full.

Full Moon

Full moon is a lunar phase that occurs when the Moon is on the opposite side of the Earth from the Sun. More precisely, a full moon occurs when the geocentric apparent (ecliptic) longitudes of the Sun and Moon differ by 180 degrees; the Moon is then in opposition with the Sun.

In astronomy, lunar orbit (also known as a Selenocentric orbit) refers to the orbit of an object around the Moon.

Types of Eclipse

SOLAR ECLIPSE

A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partially obscuring the image of the Sun for a viewer on Earth. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.

LUNAR ECLIPSE

A lunar eclipse occurs when the Moon passes behind the Earth so that the Earth blocks the Sun’s rays from striking the Moon. This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely so, with the Earth in the middle.
