3-Almost identical eclipses occur after 18 years and 11 days.
4-This period of 223 synodic months is called a saros.
5-Each year there are between 2 and 5 solar eclipses.
6-The total solar eclipse, when the Moon completely obscures the Sun and leaves only the faint solar corona, is known as a Totality.

9-If any planets are in the sky at the time of a total solar eclipse, they can be seen as points of light.
10-During a total solar eclipse, conditions in the path of totality can change quickly. Air temperatures drop and the immediate area becomes dark.
11- A solar eclipse can only occur when the Moon is close enough to the ecliptic plane during a new moon
