On Earth, the planet has a single moon and a single sun. And as long as the moon stays within a certain proximity of Earth (apparently, it's slowly drifting further away), a total eclipse occurs at a point on Earth once every 400 years or so.
That's a long time. So I'm trying to devise a hypothetical system whereby a total eclipse at the same point on the planet can occur on a much more regular basis. Ideally, I'd like this to be on once per month basis.
Initially, I thought a binary-system would help -- more objects to obscure. However, it would seem that the more suns we include in the system, the more points of failure we have, since each would need to be blocked out to form a total solar eclipse. And as soon as we start relying on multiple moons covering up multiple suns at just the right time, the probabilities start to work against us, as I understand it. If this is the case, then we're back to square-one, a single sun.
How can we maximize (greatly increase, not looking for perpetual total eclipse) the number of total solar eclipses that occur on a planet on a given point on a planet?
Can tweak anything about the solar system or planet, for example:
- Number of stars
- Number of moons
- Orbital eccentricity
For the sake of simplicity, the goldilocks-zone-related habitability concerns can be out of the remit of this question. Instead, let's just zero in on what stellar / planetary configuration can maximize the number of total eclipses for a given point on the planet.
