Answer 2

Explanation:

⏩⏩Circle of Illumination :-⏪⏪

• The circle of illumination is the circle that divides the day from night on the globe.

• It takes 365¼ days (one year) for the earth to revolve around the sun.

• Six hours saved every year are added to make one day (24 hours) over a span of four years. This surplus day is added to the month of February. Thus, every fourth year we have a leap year with 366 days.

• Earth goes around the sun in an elliptical orbit. Note that throughout its orbit, the earth is inclined in the same direction.
