All solar eclipses involve the moon passing between the Sun and the Earth, and in the process, casting a shadow upon the Earth’s surface. However, the type of eclipse that can be observed from a given location is dependable on the way the moon passes between the Earth and the Sun, whether it passes directly, or only partly between the Earth and Sun.

There is an amazing cosmic coincidence that the Moon is about 400 times closer to the Earth than the Sun. At the same time, the Sun is about 400 times larger than the Moon. What this means is that the size of the Sun and Moon as seen from the surface of the Earth is about the same in the sky. When viewed from the surface of Earth, both the moon and sun appear to be about one half degree in size – that is, about the size of your thumbnail when you extend your arm. In astronomical terms, the Sun and Moon have roughly the same angular size. This makes it possible for a solar eclipse to occur. No other planets in our solar system enjoy the same one-to-one ratio.

For a solar eclipse to occur, there are firstly two factors that must be fulfilled. Firstly, There must be a new moon. Secondly, the New Moon must be in the ecliptic, on the Line of nodes of the intersection of the ecliptic plane and the orbital plane of the moon. There are two situations that a solar eclipse can occur.
