Annular Eclipse
An annular eclipse occurs when the moon passes dead center in front of the sun but, because the moon’s orbit is elliptical and so is sometimes closer and sometimes further from Earth, it appears too small to fully cover the disk of the sun. https://eclipse2017.nasa.gov/how-eclipses-work

Path of the Solar Eclipse, October 14, 2023
On October 14, 2023, the Moon will pass directly between Earth and the Sun. It will not quite completely cover the solar disk, instead turning it into a thin "ring of fire." This annular (Latin for ring-shaped) eclipse will be visible within a roughly 125-mile-wide path from Oregon to Texas and on into Mexico, Central America, and South America. Again, North Americans outside the path will be treated to a partial solar eclipse if the weather cooperates.
