Advertisement Remember that sublime moment in Star Wars when an introspective Luke Skywalker gazes upon a double sunset on Tatooine? To our eyes, that’s some seriously exotic stuff, but binary star systems are actually quite common, representing at least half of all Sun-like stars in the Milky Way. That said, a hefty portion of these include “wide binaries,” in which distances between stellar companions exceeds 10 AU, or 10 times the average distance from the Earth to the Sun (it’s also a comparable distance between the Earth and Saturn).
