With a minimum mass comparable to that of Neptune, it is of the class of planets known as Hot Neptunes. Dynamical simulations suggest that if the mass gradient was any more than a factor of two, the system would not be stable.

Orbits of the inner planets of the HD 10180 planetary system, using the orbital configuration from an eight-body (the star and seven planets) Newtonian model taking into account tidal dissipation.

While planet c does not exist in any mean motion resonances, both planets with adjacent orbits (b and d) share near resonances with c.
