EVIDENCE FOR A DISTANT GIANT PLANET IN THE SOLAR SYSTEM

visible in the inner solar system. Iorio (2014) analyzed the effects of a distant perturber on the precession of the apsidal lines of the inner planets and suggests that, particularly for low-inclination perturbers, objects more massive than the Earth with a ∼ 200–300AU are ruled out from the data (see also Iorio 2012). ................
