What is an Annular Solar Eclipse
The word annular references a ring of bright sunlight, or annulus, known as a "ring of fire." This “ring of fire” is visible around the moon during the maximum phase of an Annular Solar Eclipse.
Annular vs Total
Annular solar eclipses and total solar eclipses are similar in that they occur when the moon passes between the sun and Earth. The moon temporarily blocks the sun and casts its shadow on Earth. The moon travels an elliptical orbit around the Earth so the distance between the two is not constant. From our perspective on earth when the moon is closer to us, it appears bigger and can block more of the sun’s light. It aligns perfectly with the sun resulting in a total solar eclipse. When the moon's orbit is further from the Earth it does not completely obscure the sun, thus an annular eclipse occurs.
When and Where Will It Happen
The 2023 Annular Eclipse will be visible across three continents, through seven U.S. states and in thirty national park units before ending at sunset in the Atlantic Ocean.
