What is Ring of Fire: A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the Sun for a viewer on Earth. An annular solar eclipse takes place when the moon's apparent diameter is smaller than that of the Sun's and blocks most of the Sun's light. This causes the Sun to look like a ring (annulus) of fire.
