Description. The line that separates day and night is called the terminator. It is also referred to as the “grey line” and the “twilight zone.” It is a fuzzy line due to our atmosphere bending sunlight. In fact, the atmosphere bends sunlight by half a degree, which is about 37 miles (60 km)

On earth day and night are different in different parts of the world according to time , and time difference is there all over the world for example when it is day in America, in India, it is night

From space, when we look the dividing line looks beautiful

Day and night happens because earth rotates on its axis

The dividing light moves all the time with the rotation of earth

This line has no place , it is imaginary line

When we see from space, earth looks beautiful
