What makes a total solar eclipse? A total solar eclipse occurs when the moon comes directly between the Earth and the Sun as viewed from a specific location on the surface. What makes this possible is the fact that the disk of the Moon and the Sun appear a similar size to an Earth observer. Because the Moon's orbit is offset from the Sun by 5 degrees this phenomena is only observable when both are at a node.
