What is an Annular Solar Eclipse?
Understanding the Annular Solar Eclipse
An annular solar eclipse occurs when the Moon passes between the Earth and the Sun but is too far from the Earth to completely cover the Sun. As a result, a glowing ring, known as the 'ring of fire', is visible around the silhouette of the Moon. This celestial event presents a stunning visual spectacle, captivating many around the globe.
The Science Behind the 'Ring of Fire'
The phenomenon is caused by the varying distances of the Moon from Earth during its elliptical orbit. When the Moon is near apogee (the farthest from Earth), it appears smaller in the sky and does not completely obscure the Sun, leading to the formation of the 'ring of fire'.
