    The compact binary system in OJ287 is modeled to contain a spinning primary black hole with an accretion disk and a non-spinning secondary black hole. Using post-Newtonian (PN) accurate equations that include 2.5PN accurate non-spinning contributions, the leading-order general relativistic and classical spin–orbit terms, the orbit of the binary black hole in OJ287 is calculated and as expected it depends on the spin of the primary black hole.
