Answer:
It's the same there is no change.
1-The longest a total solar eclipse can last is 7.5 minutes.
2-The width of the path of totality is usually about 160 km across and can sweep across an area of Earth's surface about 10,000 miles long.
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.
7-Total solar eclipses are rare, happening only once every 18 months.
8-Total solar eclipses produce harmful rays that can cause blindness.
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
Answer:
Explanation:
The distance to the Sun is 5,890,000,000,000. We need to write this distance in km.
A number can be written as 
in scientific notation where x is a real no and y is any integer.
There are 10 zeros in the given number and also there are 12 digits after. It would mean that,
So, the distance in scientific notation is :
