From the surface of a world orbiting a giant binary planet, two worlds, one potentially larger than the other, would be visible for half the time, on average. At night, they’d be far and away the most prominent features in the sky. Multiple scenarios exist that result in two planets occupying the same orbit. (DASWORTGEWAND OF PIXABAY)And one of our planets has the orbiting moons to prove it.Despite the dangers posed to planet Earth by a comet or asteroid strike, our Solar System is actually an incredibly stable place. All eight of our planets are expected to remain in their orbits, stably, for as long as the Sun remains a normal, main sequence star. But this isn’t necessarily the case for all Solar Systems.If two planets pass closely by one another in orbit, one can perturb the other, resulting in a massive orbital change. These two planets could collide, one of them could get ejected, or one could even get hurled into their central star. But there’s another possibility: these two planets could successfully share a single orbit together, remaining in orbit around their parent star indefinitely. It might seem counterintuitive, but our Solar System offers a clue to how ...
