Question Non solar/lunar eclipses in our solar system

[Catastrophe]

Those with a metaphysical bent may see some amazing coincidence in our Earth Moon system which allows total eclipses. Coincidence it is, of course, as the Moon is slowly moving away, and eventually "totality" will include a wide bright halo.

BUT what about other members of our Solar System? Do any other moons or planets mimic our Earthbound experience?

Mercury and Venus have no moons, so not there.
Mars has two small moons that are not large enough to provide totality, so not there.
Jupiter and Saturn's moons are large enough to create shadows on the cloud tops, so I assume that if you were some distance within the atmosphere's of either of those planets, you might find that balance of totality.
Not sure about Uranus or Neptune.

AHA! But what if you have more than one moon. I think you are correct to discount Mars, although what about, seen from Mars, Phobos obscuring Deimos. Can it happen? But still not a "total eclipse", more of an occultation.

"An occultation is an event that occurs when one object is hidden by another object that passes between it and the observer." Wiki.

It has happened.

Thank you for that. Most impressive! Cat

I’ve read that there are no other total eclipse events for other planets, but I accept that on logic rather than verifying the claim.

The size of the Moon relative to the sizeof Earth is highly unusual. One exception will be with Pluto and Charon, which no doubt could produce totality.

First prize to Helio. Try putting Pluto and Charon in post #6 or go:

Nice snag! Another reason I was convinced that Charon would work is that their proximity is so close that their barycenter is outside of Pluto.

Given their very long orbital period around the Sun, the time between eclipses is terrible.

This situation is provisory, because the distance Earth- Moon progressively increases because of tidal forces. In a far future there will be no total eclipses but only anular. In the remote past the Moon was nearer to Earth, and the suyb corona was not visible during total eclipses.

As I did say in post #1:

Until a few billion years from now when the earth’s rotation slows down until one side faces the moon all the time, about 47 days long. By then, it’ll be about time for the sun to puff up into a red giant and maybe swallow us all up.

Thanks, folks for the enjoyable video, contest and sundry comments.

Helio, post #9: "Given their very long orbital period around the Sun, the time between eclipses is terrible."

Ah! but during those periods:
"To an observer located on Pluto during such periods of mutual eclipses, Charon would eclipse the Sun every 6.4 days. Charon would also be eclipsed by the shadow of Pluto every 6.4 days. Likewise, an observer on Charon would observe a solar eclipse by Pluto every 6.4 days. The mutual eclipses last five years."

Yes, but the eclipse periods would only occur twice during the ~250 year orbit period. . Charon, seen from Pluto, appears over 10x larger than we see the Moon, but its orbit is inclined ~60 deg. to Pluto’s orbit.

Lots of binary and trinary asteroids so almost a guarantee a few have total eclipses.

I was going to say Charon as a guess but you answered that nicely

But think of the occultations - with 5 moons . . . . . . . . .

. . . and on that subject, how about ???????
