Occultation Omnibus

An eclipse of the third kind—an occultation—occurs when a Solar System body traverses our line of sight to some distant cosmic light source. Studies of occultations allow both the nature of the light source (single star, double or binary star, galaxy, quasar) and that of the occulting object (lunar limb, asteroid size and shape, comet, planetary atmosphere, planetary ring) to be investigated.

One can think of a form of eclipse of yet another class, though. What about when three Solar System objects line up? The three involved in solar and lunar eclipses are the Earth, Moon, and Sun, but other combinations are possible. For example, both Venus and Mercury have smaller orbits than that of our planetary domicile. Do they ever cross the face of the Sun?
