Quick Summary

An annular eclipse occurs when the Moon passes between the Sun and Earth, but is too far from Earth to completely cover the Sun. This results in a thin ring of the Sun's disk remaining visible around the Moon. This phenomenon is a type of solar eclipse, which happens when the Moon's shadow falls on Earth's surface. Unlike a total solar eclipse, where the Moon fully obscures the Sun, an annular eclipse leaves a visible "ring of fire". The apparent size of the Moon varies due to its elliptical orbit, and an annular eclipse occurs when the Moon appears smaller than the Sun.12345
