The alignment of three or more celestial bodies is known as a syzygy... at least in the Solar System, it is. This is exactly what happens when there is a solar eclipse like the one happening this week (sorry, unless you're a penguin, it’s unlikely you’ll see it). Observations in 2010 saw the outermost planet in Kepler-89A eclipsing the second outermost world in the first known planet-planet eclipse seen outside our Solar System.
Our latest calculation still suggests that there is a good chance of the event happening this April. “Kepler-89 (also known as KOI-94) was the first planetary system in which an “overlapping double transit event” was observed. We refer to this phenomenon as a planet–planet eclipse, although it is also sometimes called an exosyzygy,” Teruyuki Hirano at the Tokyo Institute of Technology, Japan, told IFLScience. Hirano and his team were the first to find evidence of this event. “To date, no other exoplanetary system has been reported to exhibit a similar phenomenon.”
