As seen from Mars on April 2, 2022, an eclipse of the Sun by the moon Phobos exhibits an annular eclipse. An annular eclipse occurs when a moon does not appear big enough to block the entire solar disc, and a ring of sunlight remains around the silhouette of the moon. Although Phobos is closer to Mars than our Moon is to Earth, its small size means that it cannot block the entirety of the Sun.
