Bailey et al. and Gomes et al. recently suggested that the 6° misalignment between the Sun’s rotational equator and the orbital plane of the major planets may be produced by forcing from the hypothetical Planet Nine on an inclined orbit. Here, we present a simple yet accurate calculation of the effect, which provides a clear description of how the Sun’s spin orientation depends on the property of Planet Nine in this scenario.
