A new theory of the motion of Phobos – a moon of Mars – has been presented. The theory is based on the problem of two fixed gravitational centers. The analytical functions appearing in this model are expressed as a series of the third order with respect to the J2 and zonal harmonics of Mars. The interaction between Phobos and Mars is described by a potential consisting of very many elements. The zonal harmonics of order ≤12 and tesseral harmonics of order ≤6 are taken into account. Interactions of Phobos with the Sun, Jupiter, Deimos – another moon of Mars, and the tidal potential of the Sun are also taken into account.
Key words: planets and satellites: individual: Phobos / methods: analytical
