What Is an Annular Solar Eclipse?

The Moon's shadow is not big enough to engulf the entire planet, so the shadow is always limited to a certain area (see map illustrations below). This area changes during the eclipse because the Moon and Earth are in constant motion: Earth continuously rotates around its axis while it orbits the Sun, and the Moon orbits Earth.

Eclipses are only Solar's visible from the area where clause Within the shadow falls, and the closer you are to the center of the shadow's path, the looks. The name «annular» comes from the Latin word for ring, «annulus.» These eclipses are named for their darkest, or maximum, point even if it only lasts less than a second. If the characteristic ring of fire is visible from even just one location, the whole eclipse is called an annular solar eclipseHowever, in most places and for most of the duration, an annular eclipse looks like a partial solar eclipse. This is also the case for total solar eclipses and for the rare hybrid solar eclipses which have an annular maximum point in some locations and a total maximum point in other locations.
