But if in this straight line, the moon is between the Sun and Earth, from our perspective on the Earth, the Sun gets hidden behind the Moon, and we call it a solar eclipse. Most of the diagrams of Solar and Lunar Eclipses that you are shown in schools. But these diagrams create some confusion.
The confusion that even though the Moon completes a revolution around the Earth each month, given the frequency, there should be solar and lunar eclipses every month. Isn’t that interesting? So why don’t we get Solar and Lunar eclipses every month?
The reason is equally interesting, and the problem is our 2-dimensional drawings. If you look at things from a 3-dimension perspective, you will understand what’s actually happening. The plane of the Earth’s orbit around the Sun, and that of the Moon’s orbit around the Earth are different.
