ECLIPSES OF THE MOON AND THE SUN An opaque object is one through which light cannot pass. When light falls on an opaque object its shadow is formed. The earth and moon are opaque objects. When the sun’s light falls on the earth and the moon, their shadows are formed and they play hide and seek.
The moon takes 29 days to go around the earth. There comes a time during this journey when the moon moves into the dark shadow of the earth. Then it gets hidden from view. We call this an eclipse of the moon or lunar eclipse. When the moon is completely in the dark shadow of the earth, it is a total lunar eclipse. When the moon is only partly hidden by the dark shadow of the earth, it is a partial lunar eclipse. When the moon comes of the shadow of the earth, the eclipse is over and the moon can be clearly seen. at the time of the eclipse, the sun, the earth and the moon are in a straight line as shown in figure. Just as the earth casts a shadow the moon also casts a shadow when sunlight falls on it. When people in the shadow of the moon cannot see the sun, it is an eclipse of the sun or a solar eclipse. see figure When the sun is completely hidden behind the shadow of the moon, it is a total solar eclipse. When the shadow of the moon hides only a part of the sun, it is a partial solar eclipse.
At the time of eclipse the sun, the moon and earth are in a straight line as shown in figure. Once the moon moves out of the line the eclipse is over and we can see the sun again.
