Eclipses The moon’s orbit around Earth is slightly tilted with respect to Earth’s orbit around the sun. When the moon’s shadow hits Earth or Earth’s shadow hits the moon , an eclipses occurs. When an object in space comes between the sun and a third object , it casts a shadow on that object , causing an eclipse to take place.

Lunar and Solar Eclipses
There are two types of eclipses ; Solar eclipses Lunar eclipses (The words solar and lunar come from the Latin words for ‘sun’ and ‘ moon’)
4
Solar Eclipses A solar eclipses occurs when the moon passes directly between Earth and the sun , blocking sunlight from Earth. The moon’s shadow then hits Earth , So a solar eclipses occurs when a new moon blocks your view of the sun.
5
Total Solar Eclipses The very darkest part of the moon’s shadow , the umbra is cone –shaped. The moon’s umbra happens to be long enough so that the point of the cone can just reach a small part of Earth’s surface. Only the people within the umbra experience a total solar eclipses.
6
Partial solar eclipses
The moon casts another part of its shadow that is less dark than the umbra . This larger part of the shadow is called the penumbra. In the penumbra , part of the sun is visible from Earth. Solar Eclipse
7
Lunar eclipses A lunar eclipse occurs at a full moon when Earth is directly between the moon and the sun. During a lunar eclipse ,Earth blocks sunlight from reaching the moon.
8
Total lunar Eclipse When the entire moon is in Earth’s umbra you see a total lunar eclipse. A total lunar eclipse can be observed at night and during Full Moon when the Moon is near one of its orbital nodes so Sun, Earth and Moon form a straight line, and the observer is located on the night side of Earth.
9
Partial lunar Eclipse A partial lunar Eclipse occurs when the moon passes partly into the umbra of Earth’s shadow. Lunar Eclipse You can watch it pass across the moon for two or three hours.
