The force model for asteroid (3200) Phaethon

We analyzed the next close encounter of Phaethon with the Earth in 2017 and found that neglecting gravitational perturbations from Neptune and Pluto, the Earth and Jupiter oblateness give an error less than 100 km in the asteroid position. Gravitational perturbations from the inner planets (including the Moon) and Jupiter are the strongest and neglecting one of them results in the asteroid position error 104-106 km.
