Dusk til Dawn: An Odd Orbit

Mercury, may not have enough of an equatorial bulge to make this
sort of thing work. I can't find any data on the matter right this
moment, alas, but the planet's slow rotation rate does not make me
optimistic.

I'd be surprised if we knew Mercury's gravitational field well
enough to design orbits that require fine-tuning precession
yet. The planet has no natural satellites, and the only
mission to visit it, Mariner 10, just did three fly-bys.
