What are the odds of finding an exoplanet with a moon the perfect size as to create a solar eclipse like on Earth where the viewer can see the sun’s corona?

Earth’s moon just happens to be the perfect size for this in relation to the sun’s size in the sky. Sure, total or partial solar eclipses happen on every planet with a moon, but how rare is it that it would be like what we see on Earth?

We can't give real numbers, because while we have observed a variety of exoplanets, we don't really have enough to give good statistics at the low mass end, and we only have a short list of *potential* exomoons. We do know that there is no other body in the solar system where the Sun's apparent radius is almost exactly the same as a moon's apparent radius. Other than that, we can only make educated guesses.

But the consensus is that it does seem like it should be extremely unusual, and it's an extraordinary coincidence that it's worked out that way on Earth.
