# Do any known exoplanetary/solar bodies have “annular” eclipses similar to Earth's?

This was somewhat inspired by this question but is a bit different: I am interested in if there are any known systems in which the angular size of the eclipsing object is almost the same as the angular size of the object being eclipsed from the surface of a planet, as is the case for the Moon and the Sun as viewed from Earth. This is the only way that one can get "annular" eclipses, or eclipses in which the host star's corona is clearly visible. This could be the case for some moons in the solar system (which requires that they eclipse at all), and at least Phobos in particular seems to have a similar angular size to the Sun as viewed from Mars,

but it could also be true for some known (or candidate) multiple-planet exoplanetary systems in which the periods of the two planets are not too different. Probably a perusal of the public Kepler candidate sample would be helpful here.

The Sun's corona is not clearly visible during an annular eclipse, only during a total eclipse that blocks the entire photosphere. (The photosphere is much brighter than the corona.) The Earth-Moon-Sun geometry is coincidentally quite unusual, in that the Moon can just barely block the photosphere, leaving the corona visible all around the visible disk. An eclipse of the Sun seen from the surface of the Moon, where the Earth blocks the photosphere, could still leave part of the corona visible (but refraction through the Earth's atmosphere could cause some interesting effects). –  Keith Thompson Sep 26 '13 at 20:28
I haven't crunched the numbers, but solar eclipses caused by a planet passing in front of the Sun as seen from the surface of a moon might be a good place to look. –  Keith Thompson Sep 26 '13 at 20:28
@KeithThompson I should mention that the title of my question was edited by Robert Cartaino, I originally asked if other bodies have eclipses that are as "spectacular" as Earth's (which is a bit subjective), annular eclipses being one particularly impressive type of eclipse. –  Guillochon Sep 26 '13 at 20:36
