totality


'The term "solar eclipse" is in fact a misnomer. An eclipse occurs when one object passes into a shadow cast by another. In a solar eclipse, the moon does not pass into the sun's shadow, but instead passes between the sun and the earth, obscuring the sun—causing the shadow. The proper term is "occultation." The moon occults the sun, casting a small shadow onto the surface of the earth. It is not a solar eclipse, but in fact an eclipse of the earth.

The earth's distance from the sun is approximately four hundred times the moon's distance from the earth. In a remarkable coincidence, the diameter of the sun happens to be approximately four hundred times the diameter of the moon. This is why the area of the moon and the sun's photosphere—its bright disk—appear roughly the same size from the perspective of earth.

A total occultation is possible only when the moon is in its new phase, and near its perigee, its closest distance to the earth. The duration of totality depends upon the orbit of the moon, never to exceed seven minutes and forty seconds.'
