How to use annulus in a sentence?

1. Alex Young:

   Annular eclipses are similar to total eclipses in that the moon, Earth and sun are aligned so that the moon moves directly in front of the Sun as viewed from Earth, but a total eclipse does not happen, that is the moon does not completely block out the visible disk of the sun because the moon is farther away and so its apparent size in the sky is [ slightly ] smaller than the sun. This means that a tiny ring of annulus of the solar disk is visible around the moon.
