Could the dips of Boyajian's Star' (KIC 8462852) have been caused by matter in our Solar system? The interval between periods of deep dips is nearly twice the orbital period of the Kepler satellite. I consider heliocentric obscuring rings in the outer Solar system that graze the line of sight to the star once per Kepler orbit. The hypothesis predicts that future dips may be observed from Earth during windows separated by a year, although their detailed structure depends on the distribution of particles along the ring. Dips observed at terrestrial sites separated by >1000 km in a direction perpendicular to Earth's orbital motion may be uncorrelated.
